Re: PCV valve for my H six ?
Not sure on a straight 6 but when I made the PCV system for my 8ba I replaced the road draft tube with a rubber grommet that a PCV valve fit in. I then routed a hose from the valve to t threaded port in the intake manifold just below the card. I left the original oil fill/breather cap in place. I used a PCV from a 231 Buick since I was advised to use a PCV from a similar displacement engine.
