The PCV, or positive crankcase ventilation, system is part of the emissions system on your Chevrolet Malibu's engine. This system uses a PCV valve, which opens as pressure builds in the engine to ventilate crankcase gases and send them to the intake to be burned. This ensures the engine does not suffer performance problems or gasket failure due to pressure buildup. When oil clogs the PCV valve on your Malibu, or if it simply fails to open or close as it should, it can result in vapors building up inside the engine, and the excess pressure can cause performance issues and oil leaks that appear suddenly. You may also notice rough idling, poor fuel efficiency, or lower horsepower, as well as excess exhaust which may indicate that the PCV valve has failed. O'Reilly Auto Parts carries PCV valves, breather elements, and more for your Chevrolet Malibu.
