What's your opinion on this PCV adapter kit for my 51 8ba. It says to remove crankcase vent tube and plug in this adapter with PCV valve. Than tee connecting hose into hose coming from vacuum port under carburetor that services wiper motor. I assume intake air comes in thru vented oil fill cap. Thanks Bill

Why are you wanting to install this conversion?

Mr Rogers -It seems to be a popular thing to do to remove blowby and prevent condensation in the crankcase as explained in the advertisement. I know a lot of people install a PVC system in their flatheads, whats your take on this- thanks in advance.

Leaving the crankcase vent open defeats the purpose of the PCV. The purpose is to give a wave aspect to the pulses of ullage air below the pistons and draw off any pressure generated from blowby of cylinder combustion gasses. One wants nothing to go out into the atmosphere as was happening from the road draft tube with a mesh filtered inlet of outside air at another point. I have no comment on putting oiley vapors near the windshield wiper vacuum source other than it might require a neoprene wiper hose?

Than your suggestion is to block off the vented oil fill cap? Most of what I read requires a source of fresh intake air?

Why back when I had a 1957 Chevrolet. I needed to install a conversion kit to meet California registration requirements. I experienced quicker than normal fouling plugs. I think because of crankcase fumes dumping into the intake manifold.

I'm doing some research and having a filtered intake air source for proper pcv operation looks to be a required component for proper operation. So now i'm more confused.

was wondering what condition your engine is in,for you to add a PVC valve does it have blow by ? you might want to do a leak down test to find out what the real problem is my 2 cents 37 RAGTOPMAN

Ragtop 8ba runs great-good compression-but it has a lot of miles and this looked to me like an upgrade. Maybe i'm overthinking this
