And - by the way - a PCV valve essentially closes during hi vacuum periods, preventing hi vacuum in the crankcase. This is why you connect to the manifold directly....if you put a breather in the system, you are putting a comparatively large quantity of unmetered air directly into the intake system, with resultant screwy results - unsteady idle, weird metering, rough/rich/lean running, etc.

What you need is the right PCV valve. You might have to do some research on this but the info is out there.
