How to Fix / Troubleshooting
Safety first: Stop the generator and allow it to cool. Use absorbent materials to prevent slips.
- Check oil level: Verify oil is not overfilled; drain to correct level if necessary.
- Inspect filter and plugs: Tighten the oil filter and any drain plugs to specified torque.
- Gaskets and seals: Visually inspect rocker cover and front/rear seals for leaks. Replace gaskets/seals if leaking.
- Breather system: Check crankcase breather hose for blockage that could cause pressure buildup and leaks.
Significant or sudden oil leaks may indicate serious engine issues; consult a technician if unsure.
