Scheme 10: REMOVAL
  1. 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.
  2. 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.
  3. If the vacuum is not felt, clean the PCV valve and ventilation hose in cleaning solvent or replace if necessary.

Scheme 11: INSPECTION
  1. Remove the PCV valve.
  2. Insert a thin stick into the PCV valve from the threaded side to check that the plunger moves.
  3. If the plunger does not move, the PCV valve is clogged. Clean it or replace.
