Component Inspection

WARNING: This page is about a different car, the 2011 Infiniti FX35. However, it is still accessible from the selected car via links, so may be relevant.
  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 ".
