    What is a PCV valve?
    The PCV (positive crankcase ventilation) valve and breather element work together within the car's emissions and ventilation systems. They serve as part of the emissions control system by recirculating unburned gases and fumes back through the intake manifold to be reburned. Therefore, these gases and vapors are not expelled through the exhaust system so air pollution is reduced.

    Why should the PCV Valve and Breather Element be replaced?


    A plugged or fouled PCV Valve can lead to the formation of damaging sludge and varnish deposits within the engine. This may lead to increased oil consumption, air filter contamination, rough engine idle or may even lead to engine failure.



    What are the benefits of replacing the PCV Valve and Breather Element?

    Loss of power, oil dilution and even engine failure are avoided.
    Oil life is extended and engine lubrication is improved.
    Oil consumption, rough idle and air filter contamination are avoided.
    Environmental pollution is reduced.
    How often should the PCV Valve and Breather Element be replaced?

    Generally, the PCV Valve should be replaced every 12 months or 12,000 miles. The breather element should be replaced at the same time or anytime it fails a visual inspection.
