Positive Crankcase Ventilation: Testing and Inspection

Inspection

1. Check the PCV hoses and connections for leaks and clogging.

2. At idle, make sure there is a clicking sound from the PCV valve when the hose between the PCV valve and intake manifold is lightly pinched with

your fingers or pliers.

^

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