Repainting a 2004 Toyota Solara’s Spoiler Using AutomotiveTouchUp.Com Paint

My wife’s convertible Solara is her pride and joy in the summer time. We bought it back in 2017 and it has proven itself to be a reliable and fun car. One issue it had was related to an aftermarket spoiler the previous owner had installed.

In 2021 we waited to take the cover off and there had been a number of hot and humid days. When we removed it, the clear coat on the spoiler was popping off. The factory paint on the car was just fine – the spoiler on the other hand looked tough and by the end of the 2022 Summer driving season it really looked bad so I knew I needed to surprise her by refinishing it.

The clear coat was peeling all over the top of the spoiler but not the bottom.

I do own a full set of automotive paint sprayers but I didn’t feel like getting them out and set up just to do a spoiler. I decided to go with AutomotiveTouchUp.Com who I had bought touch up paint from in the past and had pretty good luck with. The only issue I have ever had with them is that you will wait around four weeks for them to make and ship your paint.

The paint code for a Toyota is one the door sticker and her Solara was “Absolutely Red – 3PO” which describes the bright red on the car very well. I knew I would need primer, that base color and clear coat. I always buy extra just in case so I bought two cans 12-oz cans of each and then I waited for it to show up.

Before you do anything – read their instructions. I went with spray cans so I focused on that section – click here.

Getting Ready to Paint

The first step was to remove the spoiler from the car. This was done by removing the body push pin rivets and moving the interior cover out of the way. Don’t be surprised to find out some of the rivets are missing or broken on an old car. You can easily get them on Amazon along with a tool that makes removal very easy.

Those little push pin rivets do the job and the tool you see makes it really easy to pull them out. If you don’t have a tool use a small blade screw driver or flat edge to get under the pin-part of the rivet and lift it up.
You don’t need to completely remove the cover – just remove as many as you want to get access to the onme screw and one stud on each side that holds the spoiler.
You will see something like this on each side. Remove the machine screws first and start to back off the nut on the stud. If the spoiler stays in place, then remove the nuts completely and the spoiler will lift straight off. In my case, my wife held the spoiler so it wouldn’t fall off when the nuts were removed.
I took one look at the old stuck on seals and left them alone. Trying to remove them would only tear them up. I decided to leave them alone, re-use them and if there was a leak then I would decide whether to replace them or just put a bit of black silicone RTV gasket glue around the two holes to seal it. I didn’t want to jump right to that because if I needed to remove the spoiler again, it would tear up the seals. You can buy black rubber seal material in sheets and you cutt out whatever shape you need but I wanted to avoid that path if I could.
I put the spoiler on two wood sawhorses to do the refinishing work. Note, I added blue painter’s tape to the sawhorses right after this was taken.
I have a 5″ Dewalt orbital sander that I used with 150 then 220 grit sandpaper to remove all of the bubbled/loose clear coat. I wasn’t worried about removing everything down to the bare bare material underneath but did want a solid surface on the top and edges for the primer to grab hold of.

Painting the Car

With the surface prepped, let’s get into the painting process.

This is red primer – not the base paint. I did three coats with wet sanding at 150 grit. No matter how hard and long I shook the rattle cans, the primer would spatter / blow larger drops into the paint vs. the fine mist you want. To be honest, I was regretting not just getting out my spray guns at this point.
I applied five coats of red paint. Light coats are the way to go and what you are looking for is a nice even rich color. I was still fighting the spattering even with the paint. So I did wet sand a few times. There instructions tell you not to do this but they also didn’t have their paint spattering everywhere.
This had six coats of clear coat. I did not wet sand between. The trick is to build up a relatively thick clear coat so you can wet sand it even and then later polish it.
Let it cure for an honest day so that it is hard enough to wet sand and then use rubbing compund to polish it. Water acts as a lubricant in the very fine 1500 grit sandpaper. If you don’t use it, the grit will fill with material and be useless. I keep a bucket of water next to me and keep dunking it in there. In this photo you see a sheet of 1500 grit sand paper that I wrap around the foam block to support it when I sand. I sand the clear coat using 1500, 2000 and 3000 grit sandpaper.
This is a random orbit 6″ bonnet washer. The terry cloth surface holds the rubbing compound and you keep moving around the clear coat removing all of the fine scratches.
The result turned out great. One important thing to remember – it looks and feels cured but it isn’t. There normal one part clear coat needs 30 days to cure the rest of the way. If you wax it, you will probably watch your finish peel right off so be sure to wait.
It wasn’t perfect but way, way better and my wife as thrilled.
The spoiler had rubber bumpers under the front part where it was close to the body. I bought these little 1/4″ tall rubber self-adehsive bumpers at Ace. They looked identical to the originals and will prevent the spoiler from hitting the body for whatever reason.

Summary

Because I had the sprayers, I regretted using the rattle can approach with the spattering that I could not get rid of for whatever reason. The time I thought I would save by not setting up my finishing automotive paint sprayer I lost doing extra sanding to get a relatively smooth finish.

In terms of color, they did a great job matching. I’m writing those blog almost two months after painting and it is nearly an exact match. Only at certain angles and lighting do I think I might see a difference – it’s that close. I’ve used them for other vehicles for bottles of touchup paint and their matching is always really good.

Here’s my advice – if you don’t have a good car air sprayer, these rattle cans (spray cans) from the company will do the job. Just be prepared to do extra wet sanding but not between the clear coats.

What is the ultimate gauge of success? My wife is really happy with the results.

3/2/24 Update: The paint is still holding up just fine. No bubbles, peeling or fading.

Add A “Thumper” To A Blast Cabinet And More Than Double Your Productivity!

Okay, Ronin’s Grips started making Yugo M70 grips sometime around 2004 and rapidly added models – the challenge was that I hand polished each and every one of them. It took a ton of time, handwork and was putting my carpal tunnel through the roof. Jeff Miller of HillBilly Firearms told me to abrasive blast the grips for a better grip and a heck of a lot less handwork. I was sold – I had to change something. Jeff also gave me a few tips – get a foot control to protect the seals vs. being in the cabinet with all of the grit, put transparency film on the window of the unit to make it last longer and he told me to get a “thumper” to make the grit settle.

Well, way back in the day margins were super thin so I bought a large bench top abrasive blast cabinet from Cyclone Manufacturing in Dowagiac, MI – they are about an hour from my shop and I could pick it up along with the foot control, I got a box of transparency film either from Amazon or a local office supply store, but I had no idea what a “thumper” was or how important it is to productivity.

Fast forward to about a month ago. Abrasive blasting used to take me a while – blast, hit the cabinet or manually move the material around in the hopper, blast some more, whack the cabinet or move the material around … it gets old. It took me years to realize that this really sucks but blasting was so much better than polishing that I didn’t think much about it.

So, a “thumper” is basically and industrial vibrator (insert joke here) that uses an electric motor in a housing with off center weights on the shaft that then vibrate like crazy when the motor runs. I guess you could call it the power of Amazon but one day I was scrolling through Amazon and a suggested item came up – a concrete vibrator – and it looked like a small motor in a housing. I had 25 Galil grips I was going to blast and all of a sudden I remembered Jeff’s advice.

Okay, the power of a vibrator with a blast cabinet is that the vibrations cause the grit to shake down to the lowest point constantly. You can blast and blast and blast. The unit was $118 with free delivery and I figured I would give it a try.

It shipped from the importer, not Amazon, and showed up a few days later – it was pretty quick as I recall. The unit was very well made other than my needing to tape up a plastic junction box on the power cord that was a little cracked and I needed to attach a 120 volt plug – it was one phase and they said about 40 watts so nothing special. The machine label says – 110V, 1 phase, 40 watts, 3600 RPM – the little thing totally kicks butt and was only $49.

Here’s a close up of the label – note it says 40 watts. There are bigger units but I don’t think you need them for an abrasive blaster.

I didn’t put it on the blaster right away because I wasn’t really sure how violent it would be and I am glad I didn’t – it vibrates like you would not believe – there is nothing subtle about it – and I immediately realized two things – 1) I was going to mount it on the free standing tool bench and not the plastic blast cabinet walls or it would eventually shake loose and 2) I needed a variable speed control to tone it down some.

Try #1

Okay, so sometimes you just have to poke fun at yourself – or at least I do. I marked the bolt holes on the 3/4″ plywood bench top and mounted the vibrator. I then plugged the power cord from the vibrator into the speed controller, the controller into a surge strip and turned it on at full speed.

I wish I had a before photo or a video of what happened next but I don’t. Every single thing on that table started vibrating right off of it. Yeah, all the grit went to the bottom on the blast table but the blast table was headed to the edge of the bench too. Whoa! I hit the off switch.

Try #2

I simply took some strips of plywood and added a cradle around the legs to limit travel. That worked. Time to try blasting some stuff.

Here’s the vibrator.
Here’s the speed controller.
Another view of the strips to limit travel. Everything on the floor had been on the workbench before I turned the vibrator on the first time 🙂 By the way, the 3/4″ plywood top is screws into the stands it is on.

Actually Blasting

Folks, it is night and day different – stunningly different. Because I don’t have to stop and whack the side of the baster or reach in and move grit around, I’d bet I’m getting work done 2-3 times faster. A bench top blaster doesn’t have a very deep bottom so without a thumper, I spent a lot of time moving grit over to the pick ,up.

Another fun lesson learned. Over the years, I’ve developed the habit of putting my chin on the plexiglass as I focused on doing the work. Don’t do that. I put my chin down on the vibrating plexiglass and it felt like someone was playing the tambourine with my teeth 🙂

Those are two IMI Galil grips getting blasted. What an amazing difference.

In Conclusion

This is one time I can honestly tell you that I have one regret – I should have done this years and years ago. Wow. It was worth it! I’ve used vibrator and speed controller both extensively for a little over a month and it’s a great combo. I don’t use the slowest speed but I am closer to the low end on the dial than I am the fastest speed.

Note, I got lucky with my first purchase. I really wasn’t sure what size to buy but the 40 watt unit has worked great. I can’t imagine anyone needing a bigger unit for a blast cabinet. These generic industrial vibrators have all kinds of uses including for the movement of powders, grains, rock, etc. so they sell bigger and more powerful ones as well.

I’d highly recommend this to anyone who has a ton of blasting to do and is getting tired of having to stop and manually move grit around.


Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

How to repair a broken brake light lens with a 3M film you can buy at a car store or Amazon?

Okay, it was late the other night and I was tired. I backed up my 2021 Ram 2500 and heard the truck hit something. “Crap” I thought as I remembered my Western plow was disconnected and sitting on the ground in the area where I was backing up. Well, I hoped I had just nudged the plow frame with my rear bumper but when I got out, it turned out that one of the lights on the plow frame had busted out a golf ball sized part of the passenger side red brake light lens – it was a good thing I was going slow at least but what to do?

If you notice the scuff mark on the back edge of the light, that’s what hit the passenger side tail light and busted the lens. I’m definitely glad I wasn’t going fast.

Well, first I have to tell you I felt pretty stupid. I literally forgot the plow was back there but then my next thought was “how do I fix this?” It was about 11:15 at night, 9 degrees out and snowing. If there’s one thing I have learned about myself, it’s that my patience is gone when I am tired and that was the not the time to try and fix something. I didn’t want the light assembly to get a ton of snow in it so I just lightly stuck some duct tape on it and work on it the next day.

Looking For A Quick and Easy Fix

First thing I did was to get online and order a new right side tail light assembly (68361714AD for my Tradesman) and that will take some time to come arrive – I literally ordered it yesterday morning and am waiting as I write this. At any rate, I needed to apply a temporary fix to the busted lens. In college, I’d used a red self-adhesive tape to “patch” a busted brake light. I figured I would do something similar because I wanted the lens closed and also you can get a ticket for having either a white light showing from a brake light or an inoperable light. The other thing was given the weather and supply chain problems these days, I wasn’t sure how long I would be waiting for the replacement light assembly so off to Autozone I went.

Autozone carries two type of repair kits both from 3M – one was a roll of red colored translucent tape ($4.99) and the other was a semi-rigid red translucent film ($8.99). I opted for the latter because I could cover the hole without seams and figured it would blend in a lot better. Now I have not used the 3M tape but the one I used in college 30+ years ago faded in the sun and didn’t stick to red hot so I just wasn’t that gung ho on it but I will tell you that my general experience with 3M is that they turn out top notch stuff so I am sure it would have been better but I went with the film and not the tape.

3M High-Strength Red Lens Repair Film 03441

The package has a 3.75×7.75″ piece of thick red film. It’s stiff but it will bend and 3M says it measures about 6-6.5 mils (1 mil =1,000th of an inch) thick. For example, if a credit card is around .03 inches thick, it measures 30 mils to give you an idea.

This is the front of the package in case you are hunting for it.
I read and followed the instructions.

As you can see in the photos, it was snowing and 16 degrees out when I did the repair. I cleaned the lens real quick with 409 – a general purpose cleaner. I then wiped it dry and brought over the film and a pair of scissors.

The break in the lens had a slight curve so I worked the material around in my hands to get the basic curve I needed and trimmed the material so it could sit flat on the surface. I then removed the rear backing materials and kept pressure on it while working out air bubbles. I figured it might need the heat of my hands to both stay bent and to bond so I did this for 1-2 minutes. For some reason, after I applied the patch was when it dawned on me that I did not take a photo of the hole – why? I have no idea.

Here you can see the hole covered with the film. I have a pretty good seal except for at the bottom where all the cracks are. There’s a raised ridge there that the film cant conform to so I called it good enough and stopped there. I figure this only needs to last maybe 2-4 weeks but wanted it good enough that it can go longer if need be.
It was definitely snowing and cold. This is a piece of film left over after the patching so you can see it.
The lens cracked but did not come apart of the top right side. If you look close you can see a rectangular piece of film I stuck there just to make sure the track doesn’t get worse.
You step back a few feet and you can’t even see the film. I checked the bond the following day and it feels like the film has really bonded to the lens. I’m genuinely impressed.

The Results

I’m surprisingly happy. I didn’t know for sure if it would work but it’s holding up just fine and from a distance you wouldn’t even know it is there.

If things change, I’ll be sure to post an update but so far, so good.

3/17/24 Update – still working. This appears to be a long-lasting fix. I’ve done nothing to it and it still looks just as good as the day I applied it. No color fading or coming loose. I’m even more impressed.

2/19/22: Still holding up just fine. Nothing has changed at all – adhesion and color are just fine. I’m still waiting on the Mopar parts dealer to send me the tail light assembly. Thanks to the film I’m not in a rush and it looks just fine from a few feet away – you wouldn’t even know it is there.

2/19/2022 – still holding up just fine a week later. No sign of the plastic film letting go from the base tail light lens. It’s solid. We’ve had weather ranging from snow and 12 degrees to rain and 15 degrees. It seems to be a solid repair.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

NOCO Boost Jump Starter Batteries for Cars and Trucks Are Totally Worth It

So I went out to move my wife’s 2000 Camry with a V6 engine. It had been sitting for about a month, it was about 20 degrees outside and, of course, the battery had discharged enough that it wouldn’t turn the car over – I could hear the solenoid click and the starter would just begin to crank and then stop. Great…..

In the old days, I would have wheeled my truck or tractor over with jumper cables, given the battery a bit of a charge and the started the car. Starting some years back, I started using various battery backs with jumper cables – man do they come in handy.

I’ll tell you though, I had a bad experience with four DB Power 1200 battery packs. I wrote about them back in February 2019 and it’s interesting that I can see people searching my blog 2-4 times per month about why their DB Power pack will no longer work. Don’t buy one is all I can tell you.

What was my go-to unit with my wife’s car and in general now? A Noco Genius Boost GB40 1000 amp starter. I’ve used it to start our lawn tractor, my 1996 Land Cruiser, her car once or twice — it’s reliable and it works. I fished it out of another car where it had sat for a month in the cold and it started her car no problem.

This is my GB40 jump starter – I bought it and a storage case to protect it when bouncing around in our vehicles. It has never failed me. I do get it out before a long trip and charge it just to be safe but it’s never empty and it has always worked when I needed it.

I bought the GB40, a storage case and the combination is always with us when we go on trips. They certainly make other models as well so you can pick the combination of size and price that works for you. For our regular cars and trucks – the GB40 has worked just fine. I definitely recommend the Noco products.

How to Fix A 2016 Ford Transit With a 3.7L Ecoboost Engine That Has a P051B Error Code

So, we have a 2016 Ford Transit F150 van with the 3.7 liter EcoBoost engine. It’s actually surprising how powerful that engine is because it can launch that big rectangle! However, there is an irritating recurring issue that we’ve had and that is the “P051B – Powertrain” message when the Check Engine Light (CEL) turns on. The posts and forum threads weren’t always very clear about what to do so I figured I would write about my experience to try and help people out.

How do I read ODB2 codes?

I’ve written about it in the past, I use a BAFX ODB2 scanner that connects to my Samsung phone via Bluetooth. I then use the Torque Pro app to read error codes and reset them when needed. I’ve used this combo for years and am quite happy.

Here’s the error code in Torque Pro. There is a free Torque version and a Pro without advertising. I find ads annoying so I paid some really small amount of money to go to Pro years ago and think it is totally worth it.
The ODB2 port is located just above and to the left of the brake pedal on the lower parts of the dash panel.

What is error code P051B?

The P051B code is returned when the engine control module (ECM), or the vehicle’s powertrain control module (PCM), has detected that the engine crankcase pressure sensor is returning values that are outside of normal operating limits. Isn’t that just great?

Remember the positive crankcase ventilation (PCV) valve and exhaust gas recirculation (EGR) system that cars had when you were younger? This is related to that – the fumes inside of the engine needs to be pulled out and burned. This improves both efficiency and emissions. The sensor is reporting back pressure changes of the EGR.

Now this is where things went sideways. I had a ton of rubbish posts to read through until I found out that Ford used a different name for the sensor plus it wasn’t exactly clear about where the sensor was located on what to order.

What does Ford call the crankcase pressure sensor?

No, they couldn’t call it something that obvious. Ford calls it the Delta Pressure Feedback EGR (DPFE) sensor. So, if you are searching all over for Ecoboost and something with pressure sensor in the search text, you’re going to find a ton of confusing crap. Try searching with DPFE instead.

Trying to find out what DPFE stood for was really bugging the hell out of me. A fellow told me to go look at the official 2016 Model year ODB guide from Ford and finally, on page 120 they define it as the Delta Pressure Feedback EGR (DPFE) sensor.

One other comment – Ford has a lot of free reference information available online but you have to hunt for it. Click here and select the option for Free Resources – that includes OBD2 guides by model year, body repair and much more.

So what can cause the P051B error code?

There are a number of things that can cause this code so let me list them in the order I would check them starting with the easiest:

  1. Is the dipstick fully inserted?
  2. Is the O-ring that seals the cap in the tube intact on the dipstick?
  3. Is the engine oil overfilled?
  4. Is there water/coolant in the oil causing it to be too full? The oil will be frothy and colored like coffee with milk in it.
  5. Are any of the PCV lines cracked or otherwise knocked off?
  6. Look inside the oil fill cap – is there a ton of sludge? If so, pull off the lines and look at the valves to see if they are filled with sludge. You can pull them regardless if you want to be sure.
  7. The pressure sensor might have failed… yeah….

For me, the last two times, it has been #7. It’s getting annoying. I’m now on my third sensor. Note, if it is the sensor then it is not critical but I do like knowing whether the check engine light is telling me something new or not so having it lit all the time is very annoying for me. In other words, you can drive with the sensor having problems but you will not know if a new code is being generated unless you hook up your scanner.

I think the sensor location was a poor choice

Let me tell you that it’s my opinion that the EcoBoost has a design flaw – the crankcase pressure sensor is sitting on a PVC hose and it gets fouled out by moisture and oil. The location can vary depending on your vehicle and which EcoBoost engine you have but on my 3.7L, it’s on the driver’s side of the engine,

So that’s the Delta Pressure Feedback EGR (DPFE) sensor right there in the red circle. Note the oil fill cap in the lower right of the photo to help you get your bearings.

Why they did this, I have no idea and we are now on our third sensor. The first was replaced by the dealer right after we got the van because Ford had revised the design. That sensor then failed and I replaced it myself. It turned out to be real easy.

What to order

Now this is where things get confusing. If you search hard enough, you can find just the sensor unit itself and if Rock Auto is correct, it is the DPFE-30 unit part number FR3Z-9J460-A … but it has been discontinued. I know they revised the design of the sensor to try and reduce fouling and maybe this is the older version. I returned this to Rock Auto and did not install it. I can’t confirm DPFE-30 is the correct sensor just to be clear – I think it is the older design they revised. The part that goes into the tube looked different.

What you want to buy is the assembly that includes the tubing and the sensor. This is the current part number as of my writing this blog to the best of my knowledge: GK4Z-6758-B

Here is the brand new part fresh from the dealer – GK4Z-6758-B
Here’s a close up of the assembly’s parts label.
This is the sensor still on the tubes. It is held in place by the two black “Ears” – one on the top left of the sensor and one at the bottom left. Gently pry them up with a small blade screw driver and the unit comes right out.
This is the part that goes into the hose.

Where to buy the GK4Z-6758-B Assembly?

Okay, you can get it from your local dealership for about $81 or you can buy it online for $38-42+S&H. We were going on a trip so I didn’t have time to wait and went with the dealer. While $81 may sound like a lot, if you mail order the part next day the price difference is less than it may first seem. [Note, prices have gone up considerably due to inflation – as of 5/18/22 it is $45-55 on eBay with free shipping.]

What I have been using more and more are vendors on eBay. You’ll see photos that look like what I showed above and also less detailed drawings that just show a tube. I’d go with reputable vendors that have quite a few reviews and as high of a rating as possible.

How to remove the old tube?

First, use a small blade screw driver to slide under the retaining tab and remove the wiring harness from the sensor. With the tab slightly up, it pulls straight back.

This is the opposite end of the sensor. You need to lift that tab up front just a tad with a small blade screw driver.
The tab just has to rise over that tiny nub just above the “GL3A” printed text near the right end to then slide off.
That little black tab above the white plastic just barely has lift up and then the plug can be pulled back off the sensor.

Next is to remove the tubing from the engine. There are quick connect fittings on each end. You just push the band’s tab out and the band moves out of the slot in the PVC fittings. It helps to look at the replacement hose first to see how the tab moves. With the tab held out, you can lift the tube straight up and off the fitting. It’s actually easy once you do the first one. Again, play with the replacement and you’ll see how it works.

It’s a novel design really. Push that little grey tab to the right and it will allow the fitting to be lifted straight up off the male plug. The one at the bottom of the engine you will need to do by feel but it is the same way – feel the tab, push it out and hold the tab out while you lift.

So, the replacement assembly took less than a minute to click back into place and reconnect the wiring assembly. Done. I cleared the code and a month later, it hasn’t come back.

Lessons learned – be careful while reading on the Internet. There are some people posting stuff that have no idea what they are talking about plus the super secret different name Ford chose to use for the sensor didn’t help matters.

Follow the troubleshooting list I wrote above and if it is the sensor, it is an easy fix. It took me about 10-15 minutes being real careful and I bet the next one will take 5 minutes max. I did have a hard time sorting through all the low-value posts and hope this helps you get your engine taken care of.

5/18/2022 Update: We’ve not had the problem again since replacing the tube & sensor assembly when I wrote this. One thing though is that I do my own oil now and only use Penzoil Platinum full synthetic. I’m not sure if the better oil is reducing particulates or not but just wanted to note that.

How To Fix A Broken Vacuum Line Fitting on the Air Box or Air Filter Housing Of A 2008 Toyota Highlander And Other Models – It’s Easy and Cheap!

I’m going to leverage my inner Forrest Gump – used cars are like a box of chocolates. You never know what you are going to get. In this case, it was our 2008 Toyota Highlander. I decided to check the air filter just in case and noticed both that the vacuum lines had cracked and that someone had done a “creative” fix on a 4mm vacuum port that had snapped off.

So this vaccum line was just resting in the hole. There’s some white glue – maybe silicone and som odd metal insert.

If there’s one thing I have learned with modern computerized cars – don’t mess with their sensors or vacuum lines. You can get odd random codes thrown, lose performance, fuel efficiency, etc. So, I knew this needed to be fixed. The big problem – the vacuum fitting was cast into the airbox!! By the way, the air box is the car part that holds the air filter in this case – the air filter housing is another way of thinking of the part.

Let me start by telling you the expensive and time consuming way – buy a replacement air box. Yeah, this is going to cost you a bundle. A OEM Toyota air box will run you $275-400, used is about $100-185 and aftermarket tends to be under $60-90 and maybe iffy quality. Then there is the labor to do the actual swap – it’s going to either take your time or you are going to pay a mechanic to do it and the cost is going to go up fast. There is an easier and faster way.

My Recommended Approach

The magic fraction for today is 5/32″. Why? Because 5/32″ is almost exactly 4mm. If we get a small brass, aluminum or stainless barbed 5/32″ hose fitting with a threaded rear, we can easily fix this. I live in a rural area and this isn’t something I can easily walk into a hardware store and find so I did some searching for NPT to 5/32″ hose barb and found both 1/16″ NPT and metric fittings plus some were brass, aluminum and mystery metal. I discounted anything plastic/nylon because I wanted a stronger fitting.

Another reason I went with 1/16″ NPT is that it can fill a pretty big hole all by itself up to about 0.31″ given the taper plus I could then use a 1/16″ to 1/8″ bushing adapter if I needed to go larger.

After much digging around using Google and Amazon, I opted for an Aeromotive #15630 hose fitting made from 6061-T6 aluminum that I did order off Amazon [click here for the Amazon listing]. There was a no-name generic brass one but no spec so I didn’t go with it. By the way, searching for fittings like this really shows the limitations of general search engines to find parts. I spent a ton of time filtering through tons and tons of search results that turned up the wrong products. What a headache.

Aeromotive 15630 fitting that has 1/16″ NPT thread on ne end and a 5/32″ hose barb on the other.

Installation

The first thing to point out is that the molded vacuum fitting is above the air cleaner so you can safely work on the box without removing it from the vehicle! Any debris from drilling or sanding will land on the filter and you can vacuum it out later. If you have a used car, peak inside and make sure the air cleaner is there and intact.

If you have just the old busted remains of the hose fitting to contend with then Dremel or sand the area flat. You want the installed barb to be able to sit flat against the wall of the box.

Next, pick a drill bit that is just the same size as the tapered bottom of the thread. NPT thread is tapered so the bottom has a smaller diameter than the top. If the air box was steel, we would use a letter “C” drill bit to make a 0.242″ hole. Notice how this is slightly smaller than 1/4″ but I am betting most people do not have lettered drill bit sets so you pick a close size and run with it. We do want the hole slightly smaller in order to thread it. Because this is plastic, we are going to push forward with the metal adapter fitting while turning and let the thread on the adapter cut the thread into the plastic. We aren’t going to bother tapping it first. That’s right – don’t buy a tap to do this uness you are a tool junky and perfectionist, which is fine if you are – I get accused of that a lot.

I’d recommend you start with a bit smaller than 1/4″ where the bit is slightly smaller than the bottom of the adapter, drill the hole and see if you can press it in. If not, go to a bigger bit. If you mess up and have a slightly too big hole, all is not lost – read the “Well crap” section below 🙂

Let’s say that everything goes great and you can screw the fitting into the plastic – Once threaded in, it’s done. Just screw it in and quit. Don’t put too much torque or you can strip it. That works just fine unless the previous guy bubba’d it, which takes us to the next part of the story.

Well crap….

In my case, I had a box of chocolates moment. The previous owner or a mechanic had drilled the hole out and installed some small metal bushing that was hidden due to the white silicone on it. I have no idea what it was from. Once I discovered and removed it, the hole in the air box turned out to be just a tad bigger than the entire 1/16″ tapered thread. Argh… not what I wanted to deal with.

Dear bubba, thank you for hiding this under the white silicone. You just made my fix a bit more complex but not impossible.

Okay, I wanted to get this job and had three options, go to the hardware store and try and find a 1/16 to 1/8″ bushing, install a 1/16″ NP threaded nut on the back to hold it in position, which I also did not have, or glue the hell out of it and call it even.

Because I am always working on cars and pressure systems due to Ronin’s Grips, did have a tube of black Permatex Optimum Black Gasket Maker that I could use. Being black, it wouldn’t be so glaringly obvious. By the way, I opted not to use epoxy due to the flexible plastic walls and expected vibrations that might break down the bond with time. [2/12/24 Note: I think Permatex dropped the Optimum series and their Black Ultra should work just fine – I’m linking to the Amazon listing]

This is what I had on hand at the time and worked great. I could have used any quality black silicone RTV glue/gasket maker and gotten the same results. I tend to either have Permatex or LocTite brand products that I use the most.

First, I scuffed the surface around the hole with 100 grit sand paper so the glue could get a better grab on the surface. The second thing I did was to spray brake cleaner on the area to remove any trace oils that might prevent a good bond.

I was wearing nitrile gloves and also sprayed brake cleaner on the fitting to make sure it was clean. Gloves both keep your hands clean and also prevent you from getting oils from your skin on the parts — assuming the gloves are clean of course. Having a clean surface makes a HUGE difference in terms of how well any glue is going to stick.

Next, I applied a bead around the top of the NPT thread of the fitting and pushed it into the hole. Since I was wearing nitrile gloves, I just took a finger and smoothed the glue out a bit and let it cure for about an hour or so. You want it cured enough to hold the adapter in place – you don’t need it fully cured yet. With warmer weather it will cure faster and in cold weather it my take a long time and need a hot light or something to warm it up above 70F to get things done. Depending on what I am working on, I try to get somewhere between 60-110F. The warmer it is, the faster it will cure but don’t burn it or melt the plastic either!

This is the first pass. It’s not pretty but it will dry strong enough to hold the fitting in place while the second thicker coat is applied.

I then put a second layer of black gasket maker on and fanned it out to get a good grip and to securely hold the fitting. I then let this all cure overnight. I’ve learned long ago not to rush faster than what the adhesive’s manufacturer recommends or you are liable to ruin an otherwise good job.

Here is the second heavier coat this was meant to reinforce the part.

So, once it was fully cured I then needed to change the cracked vacuum lines which are what I noticed in the first place.

4mm Vacuum Lines

What got me started on all this in the first place was noticing that two 4mm vacuum lines were very cracked where they slid onto their respective hose barbs. This happens as rubber ages and gets brittle so finding them wasn’t surprising.

This is one of the ends that was badly split.

Fixing this is easy. You just need either real 4mm vacuum hose or 5/32 vacuum hose. You can either go with one formulated from rubber or more expensive silicone. The advantage to the latter is that it ought to last longer.

Because we own a number of aging Toyotas, I bought an assortment bag of metric sized silicone vacuum hose of Amazon some time ago. It comes with 4mm x 82″, and the 52″ lengths of 6mm, 8mm, and 12mm. It was expensive but now I have an assortment for when I need to repair small lines such as this case. [2/12/24 the vendor I bought from years ago is gone. Check out these listings of sets on Amazon – go with a vendor that has at least 30 ratings of 4-5 stars]

You can see the two pieces I replaced because the new silicone hose is shiny black and a thicker diameter.

Conclusion

Going this route saved us a ton hundreds of dollars and has held up just fine. I did this repair last fall and have not had a single problem. Yeah, the glue does make it a big of a bubba fix but it is revsersible and the fitting isn’t going to fall out. The black gasket maker has held the little barb in just fine and the hose is very supple and shows no wear at all. I hope this helps you out as well.

2/12/24 Update: My repair is still just fine. A reader pinged me that none of the Amazon links worked so I went through and updated them.

7/28/2023 Update: Everything is holding up just fine and we’ve put quite a few miles on the car since this was written in March of 2020.

4/9/2021 Update: Still holding just fine. Not one problem to report.

Why The Mophorn Pneumatic Lift Is a Huge Help When Working On Cars and Trucks But Has One Small Issue You Need To Address

Nothing like getting old and realizing that most of your joints hate you. I bring this up because I have two manual pump floor jacks that I have used countless times over the years and the oldest is probably 25 years old – literally. Well, let me put it this way – I had no problem pumping the handle to lift cars and trucks 25 years ago but starting about two years ago, the action really started to cause elbow and shoulder injuries I had to flare up. It got so bad that I had to make a choice either to stop working on vehicles or to find a different approach.

I work on cars and trucks in our driveway so a permanently installed lift was not an option. It had to be something portable. My first thought was to get a low profile air-over-hydraulic jack that is mounted in its own wheeled carrier. They have an incredible lifting capacity (around 22 tons) but they are heavy (around 80 pounds), slow (air over hydraulic is many things but fast is not one of them) and expensive (they start around $200 and just go up from there). What really stopped me was the weight and the cost. I can’t lift or drag as much weight as I used to and the entry-level units were a tad more than I wanted to spend.

So, I kept digging and ran across pneumatic/air jacks. Think of the air suspensions you see under a big rig. Basically one or more air bladders fill with air and lift the top of the jack. They max out in terms of lift height around 18 inches and 3 tons of lift but it depends on the model. Definitely spend some time researching before you buy. I found that I needed to think about:

  • How low I needed the unit to collapse down to fit under our cars to get in position prior to lifting
  • How much weight did I need to lift
  • How high I needed the unit to lift
  • How much did it weigh?
  • What was it going to cost?

I then started reading listings on Amazon plus paying careful attention to review scores. I also talked to a mechanic friend of mine about the safety of the unit and what his thoughts were. He told me to consider two things: 1) always immediately put jack stands in place and 2) don’t lave the unit out in the sun and weather thus harming the rubber. Those suggestions made a lot of sense to me.

On January 8, 2019, I wound up buying a Mophorn Pneumatic Jack, 3 Ton, Triple Air Bag, with a 16″ lift height for about $150 with free shipping. The unit arrived with just little bit of assembly needed. I recall I had to install the handle and the pressure line but that was it.

I get about 15″ of lift at 90 PSI.
Left lever is the exhaust and due to the lever design, you can adjust how slow you want to drain air out. Even if you hit it and have an “oh shit” moment, you typically have a few seconds before the vehicle starts to go down. The middle unit with the pull ring is the safety blow off valve. The far right lever is the air inlet and there is a Milton M-series male plug under the Milton quick connect female fitting. If you want a reliable air system, use Milton fittings – they last.

As you can guess from the sticker above, the lift is made in China and the instruction sheet is pretty terse but it’s really not that hard to figure out. I do want to cover a few specifications with you and convert them from metric to US customary measures – these are from the owner’s manual included in the kit unless otherwise noted:

DescriptionMetricUS
Capacity3,000 kg6,613 lbs
Air Pressure5-10 Kg/cm^271 to 142 PSI
Air pressure from label on handle – presumably the recommended pressure8 kg/cm^2113 PSI
Minimum Height145mm5.71 in
Maximum Height400mm15.75 in
Lifting Time5 seconds5 seconds
Working Temperature-69C to +50C-92F to 122F

What have I lifted with it?

When I say “lift”, I am talking about the front end or the back end – not the whole vehicle.

  • 1994 Toyota Corolla DX
  • 1996 Toyota Land Cruiser
  • 2000 Toyota Camry
  • 2006 Toyota Solara
  • 2008 Toyota Highlander
  • 2016 Ford F150 Transit
  • Others more or less along the lines of a Camry or Highlander

There are a few things I have noticed

First, let me point out that I like this unit and would recommend it but there are a few things I want to point out:

  • The highest my lift will go is 15″ and that may be a function of my only running 90 PSI to the jack
  • I don’t think it actually can lift 3 tons. It bogs down on the front of our old 96 Landcruiser and also our full size F150 Transit. Again, I think it’s my lower air pressure. This summer I might plumb a dedicated 120 PSI line and see what that does. It will depend on time and money.
  • There are stabilizing cones made from steel inside the jack. Maybe 1 in 20 lifts they need a whack to start coming down. I may polish and lube these if I get a chance.
  • The rubber is pretty thick on the bladders. With that said, I do store it indoors away from the sun and the weather. I’m writing this a year later and the bladders show zero signs of wear.

The One Little Thing You Must Do: Blue Loctite Your Screws!!

I have used my jack many times since I bought it. Starting around September I was hearing faint air leak and thought the jack had bent. When I had time I found out that the bottom screws had loosened up and air was simply escaping from between the gasket and the bottom plate. I was surprised and disappointed to note that none of the screws had any thread locker applied to any of them. Many were in varying states of coming lose.

The unit is well made. The air bladders secure to that steel plate you see on them and then that assembly bolt to the dolly.
It’s the screws that attach the bladder to the while disc-shaped plate in the previous photo that came loose. Here are the metal stabilizing cones. I wish I had polished and lubed them when I had it apart and will go back and do that at some point. I did apply air tool oil to the cones after cleaning them of a gritty dust that probably dated back to when they were manufactured.
Before re-assembly I put a thin bead of Permatex Blue RTV gasket seal on the rubber gasket and then applied Blue medium-strength Loctite to each srew and brought them down lightly. I then went criss-cross lightly bringing down each screw to firm and then applied a final torque of 11 NM (about 8 ft-lbs or 97 in-lbs.

I then did the same thing to the top plate as well just to play it safe. No more leaks.

The reassembled bladder assembly then screws back down to the baseplate of the dolly. Note, this photo is actually from when I was taking it apart. The screws were so scuffed up that I just replaced them. Did I mention I use this a lot?

The following is the exact jack on Amazon that I bought and this review is about:

Bottom Line

I would buy this again and recommend it as well – just due the Loctite thing I mentioned. Note there are other Chinese suppliers on Amazon also but they do not get as good of reviews as the Mophorn units so my recommendation is only for that brand.

How To Find Out Torque Specifications for Screws and Bolts: An Outstanding NASA Reference Guide

We’ve all been there – you’re working on a project and wondering how much to torque something so either we don’t bother or just take a guess. What I only found out recently was that in 2017, NASA published a really cool guide called “Installation Torque Tables for Noncritical Applications” – with the document ID as NASA/TM—2017-219475.

The document provides the torque specifications for a ton of general purpose fasteners that do not have an exact specification assigned – hence the term non-critical. As you can imagine, they get very specific in critical/risky situations.

At any rate, given the size of the bolt or screw, the thread pitch, the material and the depth, they provide a reference torque specification you can follow for both metric (M6, M8, M10, etc.) and SAE (#8, #10, 1/8, 1/4, 3/8, etc.) fasteners. Note, they provide an assembly torque (which is a 65% load from failure) and 100% torque. I use the assembly torque spec.

They also recommend that the depth of thread engagement be 1.5x the diameter of the fastener. So a 1/4″ (0.25″) fastener should have at least 0.25″ x 1.5 = .375″ (3/8″).

Here’s an example table. This is for fasteners going into 6061-T6 aluminum with a thread depth of 3/16″. If we go down for a 10-32 UNF screw, the assembly torque is 22.2 inch pounds. I’d use that lacking any other detailed information. I could go up to 34.2 inch pounds but I have stripped so many fasteners I don’t risk it. I’m a huge fan of Loctite so I go with that and the assembly spec.

Kudos to the two authors and to NASA for making it available. The PDF is a cool reference document and one I use whenever I can’t find a specific torque value for a given application. All you machinists and engineers – you know way more than me so please let me know if you have other resources you recommend.
