jbrentd's 2nd Chance Coupe Quattro

Postby jbrentd » Tue Sep 04, 2018 10:11 am

Hey all, I thought I would start a thread over here on for my CQ.

I originally bought the car back in Feb 2010 from the Milwaukee area. Owned it for 4 years and did a decent amount of maintenance and rehab work to it.

Day I brought it home

    Here are some highlights from when I owned it...
  • Timing belt job
  • Spec Stg 3 clutch
  • Euro front/rear bumpers and 1-piece headlights (relayed)
  • All new audio components
  • Replace heater core and rebuilt the airbox
  • Pearl white respray & some body repair




Not long after I had it repainted, I bought an A6 and the coupe didn't get much road time. I didn't want to see it sit in the driveway getting unused, so I I sold it in Feb 2014 to guy from central Kansas. It was looking like this.

After selling it, I quickly started to regret that decision. Since then, my oldest is off to college and my youngest is driving and I am finding more free time to work on a project again. So, I recently contacted the guy I sold it to and found that it has been sitting in his garage for a couple of years. He was driving it for a while, but put it away when it developed a low end knock. He has a couple other projects going and was willing to let it go. So, I bought it back. While he owned it, he did a few things like finishing the DIY coilovers that I had all of the parts for, getting the A/C system working again, and some odd and ends.

It's probably a lost cause, but I am going to do a compression and leak down test on the 7A so I know what's going on with it for sure. Buying it back feels like a bit of a risk based on the condition of the engine, but it should get me off center to do a swap that I hoped for originally.

Looks great. Glad you got back into it!

Where are you located? I have a 7a that came out of my coupe that ran/drove before I pulled it out. It needs some external parts (from yours) but the base engine is good. I chopped the harness and hoses to get it out. It's all yours if you want it, I havn't been able to even give it away.

Yesterday, I was a couple hours late in contacting a guy selling a ‘91 200 for $400 on CL. He was about 2 hrs from my house! Those don't pop up very often in my neck of the woods. It sold in a matter of hours.

Funny thing was I was complaining to a friend about 20vt cars never being available in my area and he says “what about this one?”

Coupe is in the garage...let the disassembly begin. Compression test showed no pressure in cyl #3 and we saw a couple bent valves with the borescope.

Tearing apart an engine is new territory for me, so I’ll be learning a lot as I go.

I've been working on it a little at a time and have drained the coolant and oil, removed all of the intake, valve cover and head bolts. I started to remove the exhaust manifold, but could not get to the 2 rear nuts on the bottom. So, I moved to the EM/downpipe flange. Next is to separate the head.

    Just some notes along the way:
  • I work slow!
  • There are wasp and muddobber nests EVERYWHERE on this thing. I wish I would have taken pictures of them...it would make quite a collage.
  • I probably shouldn't care about breaking/shearing bolts and that's part of the reason I am so slow.
  • I only got a very small of amount of coolant out when I drained it. But I didn't see any in the oil.

I went to put #1 at TDC and align all of the timing marks before removing the timing belt. And I think this thing is out on its timing.

In the pics below, #1 is at TDC(verified with a long 1/4” extension) and the crank pulley marks are lined up. But it looks like the cam pulley is off by a couple of teeth and the camshaft marks aren’t lining up. Am I seeing that correctly?

Doesn’t matter much anyways. But it might help explain what happened to it. Maybe it skipped a tooth? Or the PO did it intentionally hoping for performance gains?

Could dirt and debris cause the timing belt to jump? The crank, cam and water pump sprockets all had junk in the cogs.

More mud dobber nests...getting chewed up by the water pump, I guess.

Gross! Looks like you may be on to something... were all the guards in securely in place?

I would say yes. That much crud under the belt could cause the belt to skip. It kind of looks like old bits of belt, I wonder if it sat for a long time, then someone tried to just crank it up and run it.

Yes, but there were nests in there between the TB covers.

Going to inspect the cylinder walls for signs of damage and then check the piston deck height across all cylinders. If everything looks okay there, the plan is to take the head to a local machine shop to have it checked out.
