Positive Crankcase Ventilation Valve: Testing and Inspection
(1) Hold the PCV valve vacuum side down. Using light pressure, depress the thin stick of the PCV valve spring by 5 - 10 mm. Release pressure on
the stick to see if the PCV valve spring will lift the stick to its original position.
(2) If the stick returns quickly to its original position, the PCV valve is OK. If the stick does not return quickly, clean or replace the PCV valve.
