Common Faults & Troubleshooting
1. Gasket Leakage
- Causes: Deteriorated gasket, loose bolts, dirty flange
- Symptoms: Seepage, oil loss
- Solution: Replace C3906696 gasket; Clean surface; Torque correctly
2. Drain Plug Leak/Thread Damage
- Causes: Bad seal, damaged threads, over-tightening
- Symptoms: Leak at drain plug
- Solution: Replace seal; Repair threads; Use genuine magnetic plug
3. Pan Damage, Rust, Deformation
- Causes: Impact, corrosion, material fatigue
- Symptoms: Dents, cracks, leaks, rust
- Solution: Replace C2831341; Protect from impact; Inspect regularly
4. Abnormal Oil Level/Lubrication Failure
- Causes: Pan leakage, clogged suction, sensor fault
- Symptoms: Low pressure, engine noise, warning
- Solution: Replace pan; Clean suction; Inspect sensor; Change oil/filter
