Question Stock PCV valve take boost
The stock PCV valve is a check vlave by design. You can see this by trying to blow in one end. Anyways, anyone know how much boost it can take before failing?

PCV is a flow limiter at best. Use a check valve in line.

So you're saying it will fail immediatly? Whats a good check valve able to flow enough with a low enough cracking pressure?
