PCV Valve Inspection and Test
|1.||Check the PCV valve (A), hoses (B) and connections for leaks or restrictions.|
|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 (A) 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.
