Element and PCV Valve
What is a PCV system?
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.
What are the benefits of replacing the PCV Valve and Breather
- 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
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. Your Grease Monkey manager will
