Check Vehicle Fit

The PCV valve is one half of the crankcase ventilation system - the other half is the breather filter. The breather flows clean air into the crankcase through a hose on your air filter and the PCV valve lets dirty air and crankcase gases out. These dirty gases and air get sent through the engine to be re-burned for clean emissions. An old PCV valve can cause rough engine idle, blown oil seals, fouled air filter and fuel system, fumes in the passenger compartment, excessive engine part wear, and shorter oil life. Although the PCV is not a pollution control valve, a worn out PCV valve can contribute to air pollution. So, it’s important to change your PCV valve for the safety of your vehicle - and the environment!

                          A:

                          Hi Skippy, glad to help you! The PCV valve is a vital part of the emissions control system on most vehicles. The PCV valve is usually plugged into a rubber grommet in the valve cover. It may be located on or near the intake manifold. A hose leading to the PCV valve is often kept in place by a clamp. Sometimes there’s a little L-shaped housing on the end of the hose that covers the end of the valve. Locate the PCV valve and loosen the hose clamp if there is one, or pull the little L-shaped housing off the end of the valve. Some PCV valves are held in place with a rubber grommet and can just be pulled free. Others are threaded into place. If you can’t unscrew the valve by hand, try to grasp its base with the open end of a combination wrench or a small crescent wrench. Remove the hose and blow through it. If the hose is dry, brittle, soft, spongy, or full of sludge or hard deposits, you should replace it. If the clamps are rusty or the grommet looks deteriorated, you should replace them, too. If the new valve screws into place, do this by hand to avoid stripping the threads in the valve cover. Make sure that the valve is seated securely (it should stick just a little when you try to unscrew it again), but don’t over-tighten it! Start the engine, and check around the PCV valve for leaks.
