Thread: PCV valves

I have wndered about this to. I know what they are for, but for a guy like me with a 550hp stroker are they really important? I have 2 breathers on my motor, with the baffles. You catch the smell of oil every once in a while. But I have had no problems running like this. It makes since to me that you would want new clean air being shoved into your intake, not hot old air.
Someone educate us!...lol

yup the vacuum actually pulls the crankcase pressure/vapors out of the crankcase and is able to burn in the combustion chambers.... i've seen cars without a pcv run terrible.... my buddy got a fully restored 66 charger for $2500 because of this... the guy built the car and dumped thousands into it, rebuilt the 440 and everything but just couldn't get it to run right, he finally got so frustrated he sold it to my friend for $2500.... my friend added a pcv to the car and it now runs like its brand new
