Component Inspection

WARNING: This page is about a different car, the 2013 Infiniti FX37. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK 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 "REMOVAL AND INSTALLATION ".
