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. Removes blow-by gases out of the crankcase. Engineered for OE fit, form and function. Ensures clean airflow to help prevent engine wear. Helps to maintain optimum engine operation and efficiency
Don't Forget About Your PCV Valve!
A PCV Valve is a maintenance item that should be replaced as often as every 30,000 miles (refer to your Owners Manual for recommended service intervals). Overextending the PCV Valve’s service life promotes sludge formation, which clogs the engine’s interior surfaces and can lead to condensation that causes engine wear.
Common symptoms of a faulty PCV Valve include:
Oil leaks / Oil in the Air Filter housing
Excessive Oil consumption
Gray-white smoke from the tailpipe
Check Engine Light illuminated (common codes include P0171 and P0174)
Service Tip: Remove the PCV Valve and gently shake it - if it does not rattle, the valve is clogged or dirty and should be replaced. A PCV Valve that rattles might still need to be replaced if it has been distorted inside by heat, oil exposure, and/or abrasion so that it leaks air.
