The PCV, or positive crankcase ventilation valve, is a vital engine component. Although small, it performs the necessary task of removing combustion gases from the crankcase and sending them through the intake manifold to be burnt again. This reduces the pressure within the engine's crankcase, as well as helping to reduce emissions by recirculating the combustion gases back into the engine and burning them a second time. Although it is one of the most overlooked engine components, the PCV should be changed at least every 50,000 miles.
