Good to know it will help, a lot of people liked it. I was pretty surprised when I did it because there wasn't another one out there, I'm sure a lot of people, probably some members here, have done it.

Like it was stolen from the dealer yesterday.

Seriously though, it's nice to know everything mechanical is in good condition, now I have to find all the squeaks coming from the rear of the car... If you (or anyone) is around Albany, let me know, you're welcome to drive it, as long as you let me help rebuild the motor.

Got a question...what exactly is "lapping the valves"? I've never rebuilt an engine before, so a few of the terms are a bit new to me.

Lapping the valves is slightly grinding the valve seat to make a better seal. What you do is put a little valve lapping compound (slightly abrasive goo, kind of like toothpaste) on the valve, and feed it through the guide. Then you rotate it so that it sands down the seat, there are a lot of different ways to hold/rotate it, but the D series heads have plenty of room to stick an electric drill on the end. So you rotate it with the drill or something, and it makes a nice shiny seat and valve.

i read the write up, and it sounds like you left the crank/main caps in place and the motor in the car?
did you cover up the crank with anything to keep junk out of the rod journals? Just curious as I'm thinking about doing this to my newest project Si...

Actually, no, I didn't. I used a lot of oil and washed it out with more oil and then carb cleaner afterward, and I wiped off all the journals by hand. If I were doing it again (and soon I will be), I would take the motor out, or at least take EVERYTHING off of it with it in the car. At the time I was working mostly out of the manual, I really didn't know much about cars, but I needed to do it. I've had a lot of criticism about that, and about honing the cylinders myself. I can tell you it was fine though, it never burned a drop of oil, until the wrist pin seized and the rod snapped, punching a hole in the block and sending all the oil onto the radiator/firewall...

I'm planning on rebuilding/building the bottom end of my mini-me when I get back from my summer job. I haven't decided yet if i want the hassle of removing the motor. I've done rings in Hondas in 2 or 3 hours, with the motor in-car, though it would be easier out of the car, it takes a lot longer, and when you're working alone it's just less of a hassle to leave it in. It's just more opportunity for a lot of other things to go wrong. I had the hoist break on me once with the A6 hanging from it! Also think of all the other things you have to deal with, tranny fluid, removing the axles, I personally like to take out the radiator when pulling the motor. That's just a lot of opportunity to break other parts.

I think i'm going to try this, the head's already off the engine, all i need to do is take the oil pan off, and the rods/pistons out.
Last build i did was a complete teardown and machine shop and rebuild and it was the strongest A6 I had driven. I am going to cover the crank in towels and then do the same hone then carb+brake cleaner and assembly lube the heck out of everything and see how it goes.

Carb cleaner is good stuff because it comes out of the can at almost any angle, and it seems to have very high pressure.

Tom,
I was wondering if you replaced any of the bearings?
I am doing a complete A6 turbo build.

Great write up :D ..At first i wanted to swap the engine but this seems to be cheaper and more hands on than just swaping it outright., plus my engine still strong and i'm going to be doing this to learn.. I guess it's ok to leave the bottom end in the car and taking it apart . i won't be worring about the cherry picker .. thanx :bounce:
