whats a really good check valve that will flow for pcv vacuum while not in boost and while in boost it will block reverse flow?

i have my black box running to my compressor and i want to run the valve cover barb to the charge pipe but not unless i have a very good check valve on it. right now its venting and stinks when i have the heat on

 

Use a brake booster check valve

 

how do those home depot in line catch cans work while having pressure in the wrong direction?

REALLY nice check vavle, but I'm sure quite expensive. I don't know how expensive, because we have an account with them @ my work, so that stuff is free 99.

 

where are the prices!

 

Go to the well/sewage part of Home Depot and get a priming valve. I have a 1" priming valve on my BOV so that my MAF doesn't freak out at idle. Smaller ones would work wonders on the PCV system.

FYI, the oil seperators DON'T stop your crankcase from becoming pressurized. They just filter oil vapor out.

thank you and i know about the oil separators, i was asking because they only flow one way.
