I have a 2000 Audi TT Turbo. I recently replaced my head gaskets & had the cylinder head rebuilt. After i installed the cylinder head the car drove fine for about 1 day. After a week of having this done the car started to smoke out of the tail pipe. The smoke smells like oil & oil drips out of the exhaust. It smokes & drips a lot of oil from the exhaust. Im thinking that the piston rings are worn or broken. I did a compression test with the engine cold & these were my results:

Dry Test

Cylinder 1- 90 PSI
Cylinder 2- 85 PSI
Cylinder 3- 80 PSI
Cylinder 4- 82 PSI

Wet Test

Cylinder 1- 105 PSI
Cylinder 2- 110 PSI
Cylinder 3- 110 PSI
Cylinder 4- 105 PSI

What do you all think? Any suggestions are greatly appreciated.

 

The engine has to be at temp for the numbers to mean anything. 120 is the min and all of them need to be within 10% from high to low.

You did use new head bolts correct as the stocks are not reusable?

 

How positive are you on your timing job?
What color is the smoke?
Try draining some oil out of the pan. Is it black or milky colored?
