- Disconnect the ventilation hose from the positive crankcase ventilation (PCV) valve. Remove the PCV valve from the rocker cover and reconnect it to the ventilation hose.
- Run the engine at idle. Put a finger on the open end of the PCV valve to verify that the intake manifold vacuum can be felt. NOTE: The plunger inside the PCV valve will move back and forth.
- If the vacuum is not felt, clean the PCV valve and ventilation hose in cleaning solvent or replace if necessary.
Scheme 11
- Remove the PCV valve.
- Insert a thin stick into the PCV valve from the threaded side to check that the plunger moves.
- If the plunger does not move, the PCV valve is clogged. Clean it or replace.
