Inspection

1. After disconnecting the vapor hose from the PCV valve, remove the PCV valve. Visually check for a collapsed vapor hose or hose leaks.
2. Reconnect the PCV valve to the vapor hose.
3. Run the engine at idle, then put a finger over the open end of the PCV valve and make sure that intake manifold vacuum can be felt.
The plunger inside the PCV valve will move back and forth at vacuum.
