A PCV valve is a useful device and one of the oldest emission control components in most vehicles. This valve returns partially burned gases from the crankcase through the one-way valve back into the combustion chamber to be re-burned.

Once you locate the valve cover, you can proceed with its replacement by disconnecting the PCV valve hose. The valve can be removed using your hands or a pair of pliers.

The new valve should be reconnected by reattaching the rubber hose from the intake manifold, aligning the outlet connection.
