Reply to "To PCV or Not to PCV??"

Positive Crankcase Ventilation: This is the Automotive Industries answer to controlling SMOG and they found out that it helped the rings seal better during the combustion process. Hot rods have since used vacumm pumps to do the same function and bypass the Carb as the pump source and not keep the intake as clean as possible to promote better combustion. Most if not all race engines run a Positive Crankcase Ventilation system to promote ring sealing.
