Besides, the PCV valve also helps keeping the oil and the engine in proper shape extending their life as well. Also, its mechanism is very important for preventing the appearance of engine corrosion as well as it helps improving fuel economy. The PCV valve routes crankcase partially burned gases back to the engine.
Since the engine demands more air/fuel mixture at high engine speeds, the escalation of crankcase vapours into the combustion chambers should not affect performance. The PCV valve also acts as a flame trap.
