You have to have some place for the air to be drawn in.

Patrick, help me out here. It was always my understanding that the PCV (Positive Crankcase Ventilation) valve was designed to vent pressure from inside the engine that was a result of combustion gasses bypassing the rings, a common and unavoidable process. I was unaware that any form of fresh air intake was necessary...in fact, as I understand it, the PVC system requires pressure in the crankcase and a vent could prohibit pressure from building.

Please set me straight on the function of the PVC valve/system....

Thanks!

Cheers!

You gotta have an entry point for the fresh air draw on a PCV system, whether it be "open" or "closed." You don't just rely on the blowby pressure. Here's a decent write-up on PCV systems PCV Systems - Google Books and I think we've had at least a dozen good threads on them here as well.

That is absolutely gorgeous! The side exhaust may not be period correct for this car but it certainly looks fine. I like your current engine look much better.

Thank you...I think once the black wires and cap are in place, it will have that muted look that I prefer...red wires are a bit custom hot rod to me. I would like to keep it more original in appearance.
