The Positive Crankcase Ventilation (PCV) valve is part of a system which is designed to protect the atmosphere from harmful vapors. Blow-by gas from the crankcase, as well as fumes from crankcase oil are diverted into the combustion chamber where they are burned during engine operation. Proper operation of this system will improve engine performance as well as decrease the amount of harmful vapors released into the atmosphere.
