I agree, but I only have excess oil when the turbo boosts, basically I think its sucking it out of the engine through the catch can. In the pic below you can see how its set up. The line on the far left at the bottom of the can is going to to the intake.
The line on the top on the elbow is coming from the right head breather, basically it would act like a vacume pump under any sort of boost. I think.
Im of the opinion the lines need to be swapped around and the problem will be solved.
