Positive Crankcase Ventilation (PCV) valves

[Jacques Reed]

Not familiar with the Chev Blitz PCV valve setup but here are two types that I know of used on Ford sidevalve/flathead V8 engines.

One type has the PCV valve feeding directly into the manifold at the rear side of the carby and the other has a spectacle piece between the carby and manifold and the PCV valve is fed into the front side of this piece just below the carby.

This front feed is the same as shown in my Ford CMP parts and maintenance manuals.

Hope this is of some interest.

Cheers,

Jacques
