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 positive crankcase ventilation or PCV valve is an inexpensive and often overlooked component. It is also one possible cause of expensive oil leaks and sludge buildup in an engine. All automotive engines are lubricated with oil and when oil is churned by moving parts, pressure is produced. Piston rings and valve guides also leak slightly producing pressure in the crankcase. Many years ago, they simply vented the pressure into the atmosphere with a road-draft tube and breather cap. Today we use a positive crankcase ventilation or PCV system to handle this and other task. How the PCV system works. The PCV system is relatively simple. An inlet hose connects to a filtered air source. This is used to supply clean air that is drawn through the engine.
