Shop Shots Volume 70 Insider Pictures of Automotive Service

HOLY COW!
mk1 VR6 Cabby I didn’t realize that it has been over 3 months since the last volume of Shop Shots! That is just insane. Well let me tell you guys about what has been going on around the Humble Mechanic garage lately.

At the shop
We are short handed at work. That can make for a nice pay check, but always makes for more work. Not just more cars, more nick-knack type stuff too. I also feel like VW is in the middle of a strange transition period. We are doing much more maintenance than before. The cars are getting better, but when they break it seems to be in really crazy ways. I will probably save more of my thoughts for another time. It just “feels” different.

At the house
We do a ton of spring planting in the garden. Those of you that have been around a while may remember my wife and I moved about a year and a half ago. We bought a house with a much bigger garage and 3.6 acres. That means plenty of yard work and tons of planting. We planted about 15 trees this spring. Along with the trees we planted lots of support plants too. Let’s just say we are on track to build a food oasis.

Project “Luv A Dub”
A few weeks ago I had my first real break down in the Cabby. It turned out the main engine connector came loose and shut the car down. I also feel like the torque of the engine is a little much for the engine mounts. I ordered a 4th mount from my boys at Euro-wise. Once that comes in I will start driving it a little more.

Okay, enough yapping, let’s get to the Shop Shots!

Poor exhaust repairI always love a great DIY repair. There are times when you can hodgepodge parts together to fix a problem. I am a big fan of that. I did plenty of that type of thing on the Cabby. This is the exact opposite of a good DIY. This is a nightmare.

You are looking at about 1 foot of exhaust on a Jetta. In this one foot section, you can see:

  • 4 clamps
  • 2 attempts at hangers
  • a bolt through a hanger that shouldn’t be there
  • some type of plastic “sealing” the exhaust

As you can see this is not a factory repair. If this car was in for state inspection, it would fail!

Turbo Carbon build up

If you drive a 2.0t VW, you may have heard of this issue. Carbon building up on the back of the intake valves. This is actually an issue on almost all gas engines with direct injection. The issue usually shows itself as a check engine light, or as misfires when the engine is cold.

There are a few theories floating around about what is causing this. One that makes the most sense is from the folks at B.G.(they make oil and fuel treatments). They say it is due to a small amount of fuel left unburnt when the engine is shut off. This can settle on the intake valves when they are open. That varnish catches small deposits of oil as it comes through the intake runner.

That is probably the most sound theory I have heard. We have tried a few different methods to clean the valves. Sadly the best way is to clean it by hand. Some shops use a modified walnut blaster. Other shops soak and scrape each valve by hand. Either way, it is a messy and expensive job. The next time I have the chance, I will snap a “post cleaning” picture for you guys.

VW transmission problemsThis is one of those things you see happen to a car and think “how in the world did that happen?” This is a small hole in a transmission. You would not see this hole with the transmission installed in the car. Something on the inside of the transmission broke. That break caused inside parts of the transmission to become outside parts.

I don’t think the tech working on it found the exact failure. Some parts have what is called a “core charge”. That means we have to send the part replace back to VW. Often times we do not disassemble core parts. VW can be strict about what they will and will not take back.

That wraps up another volume of Shop Shots. I know that it has been on a big time hiatus, and for that I am sorry. When the blog was young, I committed to do a blog post 5 days a week. I don’t think that I can keep that level of posting up. But I have recommitted to putting content out for you guys. If you have any topics you want us to talk about, please use the contact me form and let me know!
