• Other Names:

  Valve CP Control

• Description:

  The PCV (positive crankcase ventilation) valve (11810AA100) reroutes the gases generated by the crankcase into the combustion chambers. This prevents the gases from mixing with motor oil, forming a corrosive sludge that can clog your engine. While there is no recommended mileage when replacing this component, you should watch out for indications of a faulty PCV valve.
  

  Oil leaks can occur due to oil clogs left by the gases passing through the valve. Another indication is blown-out gaskets, noises coming from the engine, and a check engine light that is on. You can also perform a manual checkup on the breather element. If it’s contaminated with oil or hydrocarbons, your PCV valve is failing. Moreover, the clogs will affect the air/fuel mixture, which could lead to decreased fuel economy and poor overall performance.
