did you use a 3sgte oil pan or the stock 5s one and drill your line into it.
something somewhere is either

A: applying pressure to your valve cover forcing oil into the compression chamber,


B: the center section on your turbo has a leak.

My vote is for the latter.
Your drain line should be mounted on the pan as high as possible. It work via gravity.
Im guessing you have a restrictor in the oil feed to make sure your oil pressure doesnt blow your seals out right?
yah its as high as possible and its resturcted via presure regukator and i cant go any lower safely
Well,,,, you could always run the return line to a vented catch can and THEN to the oil pan. That would Definitly clear up the problem if that is indeed the problem. It could be done for less than $100 and would look hella nice. wink.gif
