Oil in the turbo outlet pipe.
 

Lots of it.

Started to work on the wife A4 1.8T 2003, to replace timing belt. When we got to the pipe coming out of the turbo oil came out of the pipe, at least 1/2 liter. Common problem? turbo seals gone?

The car as been using alot of oil between changes, something like 2 liters. I guess i know where it goes now.
