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.
A hose connects the top of the PCV valve to a vacuum port on the throttle body, carburetor or intake manifold. This allows the vapors to be siphoned directly into the engine. Because the PCV system pulls air and blow by gases into the intake manifold, it has the same effect on the air/fuel mixture as a vacuum leak.
