Required Service

The PCV system may require service for obstructions if any of the following conditions exist:
- Rough idle.
- Stalling or low idle speed.
- Oil leaks.
- Oil in air cleaner.
- Sludge in engine.
A leaking PCV valve or hose could cause:
- Rough idle.
- Stalling.
- High idle speed.
If engine idles rough, check for clogged PCV valve, or for plugged or broken PCV hoses BEFORE adjusting idle. Check PCV valve application to ensure valve is fitted. Replace PCV valve if required.
