REMOVAL & INSTALLATION



PCV Valve

Most vehicles do not have a replaceable PCV valve, they use metering jets within the PCV hoses. The only service procedure is to clean out the PCV hoses if they become clogged.

  1. Detach the ventilation hose from the PCV valve.
  2.  
  3. Remove the PCV valve. If its base is threaded, unscrew the valve; otherwise, simply pull the valve from its retaining grommet.
  4.  

To install:

  1. Depending on the type of valve, either screw in the replacement PCV valve or push it into its retaining grommet.
  2.  
  3. Slide the ventilation hose onto the end of the PCV valve.
  4.
