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 manifold vacuum is highest at low engine speeds, the PCV plunger will be drawn forward to a position that will restrict crankcase ventilation to a minimum thus ensuring no unsettlement of the air/fuel mixture.
