Re: PCV Valve Noise
I really don't beleive you can hear the PCV valve while it is installed and the engine is running.
I bet it is your exhaust clapper valve, and you just think it is the PCV. The 75 engines had this clapper in the exhaust that hooked up to the EGR valve under the carb.
Exhaust Gas Recirculator. If the engine is working, I would not mess with those things, as your repairs (if you touch it) will get real expensive real fast.
What is life worth, if everything comes easy...?
