PCV VALVE CHECK
1. Disconnect the PCV hose from the PCV valve.
2. Remove the PCV valve from the rocker cover assembly.
3. Using a thin rod, move the rod back and forth on the rocker cover side and check if the plunger moves.
4. If the plunger does not move, there is a clogging in the PCV valve. In this case, clean or replace the PCV valve.
