Pcv Check Valve For Boost. most boosting kits will add a dedicated check valve if the factory pcv is not sturdy enough to resist boost pressure, but this only prevents us from adding to the existing crankcase pressure. high flow, low cracking pressure flapper style check valve with dual inlet and dual outlet ports. Ideal for pcv systems, allows connecting two vacuum. you can try a standard routed pcv but with a strong one way check valve inline with it, another option is run two closed style breathers with. when the pcv is actively sucking air, the check valve in the vent closes forcing the crank case into a vacuum situation. i would put a check valve on the pcv valve, and run an inlet to the crankcase from pre boost (near the air filter). pcv check valve also stuck closed (it's a ball style valve, it can be cleaned), easy to remove with a 19mm. you can see the pcv valve is located in a t with a check valve on the vacuum line and boost pressure applied to one side of the pcv.
