- Symptoms: Seepage/drips around head, cooler leaks, regulator leaks, low oil pressure
- Solution: Replace 3955034 + full gasket set; clean surfaces, torque to spec
2. Abnormal Oil Pressure
- Causes: Stuck/worn regulator, bypass failure, clogged galleries/cooler, corrosion
- Symptoms: Low idle pressure, high high-speed pressure, warning light, power loss, wear
- Solution: Clean/replace regulator/bypass; clear galleries; replace 3955034 if needed
3. Poor Cooling
- Causes: Warped cooler face, poor seal, clogged core, water gallery corrosion
- Symptoms: High oil temp (>115°C), rapid oil degradation, overheating, high fuel consumption
- Solution: Replace 3955034 + oil cooler; flush coolant; check thermostat/radiator
4. Deformation/Cracking
- Causes: Over-torque, thermal shock, fatigue, impact, casting defects
- Symptoms: Warping, cracks, leaks, loose fit, oil loss
- Solution: Replace with genuine 3955034; avoid over-tightening
5. Thread Damage
