I just got some offenhauser valve covers and they have no port for a PCV valve. So I can get a Vent/Filler Cap with a PCV connector in it but I have a few concerns
1) I always thought you vented one valve cover and put the PCV on the other creating correct ventilation. That said if I put a PCV in addition to a vent cap on the same valve cover I can't cross the vent the case. Correct Assumption?
2) The vent placement is different on the new valve covers so the splash plate that would be behing the PCV is no longer under the PCV. Is this an issue?
3) Can I just vent both valve covers and skip the PCV all together?
Engine is a 62 Buick 215 v8.

Must you cut into Offenhausers ? Kinda like doing open heart surgery in your home on your favorite pet... I know your vehicle is not a '57 Chevy, but in 1957, the V8's were only vented by the oil filler cap which was on the end of the tube that was poked into the intake manifold. The first guy that answered the question seems pretty knowledgeable by my experiences on OldRide, I would go with him, vent it at the oil filler cap, and leave it at that, rather than cut into Offenhauser valve covers (ouch...), or I can maybe trade you some other valve covers for your Offenhausers (LOL)
if memory serves mecorrect the ftller cap was vented. i would try a vented cap ,if it meets emission requirements in your location,pcvs came inabout 1963.
