I have a Subaru Turbo, and my question is! Can i switch the oil in and the oil out lines
The Problem: I have to switch them because of space problems!!!

 

nope, oil in has to be oil in, and oil out has to be oil out....

 

What you need to do is clock the center section so the oil in is on top, and out on bottom. You also need to keep in mind that the angle between the drain should be no more than 30* from vertical. The oil feed is pressurized, but the drain is graivty fed.
