PCV Valve Inspection

  1. Remove the engine cover (see step 6 under ENGINE REMOVAL ).
  2. Check the PCV valve (A), the hoses (B), and the connections for leaks or restrictions.

  3. At idle, listen to the PCV valve (A) with a stethoscope as you lightly pinch the PCV hose (B) with your fingers or pliers several times. Each time the hose is pinched, the valve should click.

    If there is no clicking sound, check the PCV valve grommet for cracks or damage. If the grommet is OK, replace the PCV valve (see PCV VALVE INSPECTION  ) and recheck.
