Oil return line for audi 90 2.8?
 

Ok I have a pretty good idea of how I want to design my turbo kit. The one thing I can't think of is how to run the oil return line for this engine. The car has an upper and lower oil pan, so I don't know the best place to tap into it. I'm guessing upper pan is the best place to go, but it has a lot of baffles in it so i don't know the best place to drill. How does the return line go on the 2.7 biturbo?

Maybe there is another way, any ideas?

thanx
