what does pcv stand for
Thus the PCV valve extends the life of the oil and engine. The PCV valve requires little maintenance. The valve and filter should be replaced somewhere around 30,000 to 50,000 miles(see the vehicle owners manual for service intervals). PCV is an acronym for Positive Crankcase Ventilation.This valve is needed to relieve the pressure built up in the crankcase that is created by the heating of the air inside the engine. If this valve were not present and the pressure went unchecked, it would blow out the seals and gaskets inside your engine.PCV stands for Positive Crankcase Ventilation.This replaceable valve replaced the vent pipe on the engine, this got rid of the fumes and or pressure that builds up in the crankcase, nowadays the crankcase does not vent into the environment.   The PCV valve is located on the right side of the engine, between the base of the oil filter and the base of the PCV valve which is located near the front of the e â¦ ngine just below the thermostat housing. Locate the oil filter then look toward the front of the engine.
