Do you have any extra stock pvc system I can buyI am running 30psi on the factory PCV system with no issues.
As long as you are venting crank pressure to atmosphere you will have issues, crank pressure must be sucked out through vacuum or it gets to high, especially with forced induction engines. Some big old V8 blocks can get away with venting to atmosphere.
A catch can will not help vent crank pressure, it is a resistance in the path of air flow. Catch cans are designed to catch some of the oil carried in the crank gasses to reduce the amount going back into the engine.
You could by a PCV vacuum pump and two catch cans and vent crank pressure to atmosphere, if you buy quality parts and set it up properly it could perform as good as the factory PCV system did. This will cost over 300$, or you could reinstall the factory PCV system and put the money towards something else like brakes, suspension or swaybar upgrades...
