Re: How to add a PCV Valve to a 1949 Packard

What would be interesting to know is the specs on the Packard PCV valve. It looks like an ordinary check valve but with the crankcase products feeding directly into the intake manifold I imagine it would be quite different than the later cars feeding into an air cleaner. There must be some opening or closing parameters so engine performance would not be adversely affected by too much extra air in the fuel mix.
