Component Inspection

  1. CHECK POSITIVE CRANKCASE VENTILATION (PCV) VALVE

    With engine running at idle, remove PCV valve from rocker cover. A properly working valve makes a hissing noise as air passes through it. A strong vacuum should be felt immediately when a finger is placed over valve inlet.

    Is the inspection result normal? 

    YES: INSPECTION END

    NO: Replace PCV valve. Refer to "EXPLODED VIEW ".
