block off pcv valve?

Post specifics about what you have and what you desire. Running PCV and breathers simultaneously is not a great idea (you have unmetered air issues).
The crankcase ventillation equalizes crankcase pressure - it's flow is bi-directional.
Good luck.

well i have.. thumpers, typhoon intake *which doesnt use the lil screen*, 2021 crane cam.. (high lift).. its a street/track car.. i daily drive it everyday.. and i installed a filter system between the pcv hoses and instead of getting rid of blowby or oil coming up and getting into the intake, it just sucked the oil out the filter under hard vaccum.. 4th gear and you get on it a bit.. throttles open more than the rpms are turning.. making tons of vaccum
manifold vacuum is inversely proportionate to how far the throttle is open per delta-time.
E.g., at WOT, there's almost no vacuum.
But at WOT, there's the most crankcase pressure - that will test the flowing ability of your crankcase ventillation. The screen/baffle for the intake helps a lot.
Do you use a fuel filter type of inline filter, or a separator? The trap in the separator helps keep oil from being scavenged and recirculated at WOT.
