Oil catch can help
#12
Did you get a sealed (closed system) or open can? If you are using a sealed can, then you shouldn't "T" the 2 lines together because you are boosted. Intake manifold pressure builds up when under boost and if you are still using the PCV inlet to the intake, boost pressure will push through and into the front breather, pressurizing the valve cover. You can "T" an open can but then the PCV inlet to the intake need to be plugged, otherwise you'll just be boosting out the catch can. With my open system and "T", stock PCV valve, PCV inlet to intake plugged, daily driver, over a period of about a year, I get a total of about 100cc of fluid, 90% of which is water condensate, the rest oil, this in about 15,000 Kms. 10 years boosted, last 4 years with high boost pulley, fairly consistent catch can contents. I don't track.
