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.
The PCV valve is only one part of the PCV system, which is essentially a variable and calibrated air leak, whereby the engine returns its crankcase combustion gases to the air intake.he PCV system just diverts a small percentage of this air via the breather to the crankcase before allowing it to be drawn back into the intake tract again. It is an open system in that fresh exterior air is continuously used to flush contaminants from the crankcase and into the combustion chamber.
