Did any of the 62-65 Mopars have a PCV valve? I ran the original 2 bbl fine with breather cap hooked directly to manifold vacuum, not even thinking about a PCV valve.
However with a 4 bbl on there and the new Poly manifold – it most def needed a PCV valve to idle correctly. Hooked up an early GM PCV valve inline, but wondering what others have done.
