Positive Crankcase Ventilation Valve: Testing and Inspection
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 hose for cracks or damage. If the hose is OK, replace the PCV valve and recheck.
