Would like some ideas on installing a PVC on my 261chevy engine. it has a crankcase blow by tube. No ventilation in the valve cover. It's a aftermarket finned aluminum cover. It's a new (just rebuilt) engine and was leaking oil from the back corner. I removed the cover, found it was warped. So I had it machined back flat.So I'd like to put a PVC valve either in the cover or insert a freeze plug, drilled out for the PVC in place of the blow-by tube?
