I've had some similar issues with my current setup and excessive oil in the intake system. I had vented all crankcase breathers but would still see substantial amounts of oil in the intake until I disconnected (pulled hoses) the PCV valve from the intake pipe.
Intake is now clean as a whistle. This valve is supposed to stay closed under positive manifold pressure and only open under vacum. It's located under the throttle body and next to the turbo. I believe it has a "T" like fitting with one hose attached to the throttle body (this is where the actual valve is located), one in the block, and the other going to the turbo inlet pipe.
When you disconnect it make sure you plug your intake hole or you will run lean.
I'm fairly confident this is your problem.
