- Rear Main Seal Oil LeakModerate
The rear main seal between engine and gearbox degrades over time, causing oil to leak into the bellhousing area. Often mistaken for IMS failure.
- Coolant Pipe FailuresModerate
The coolant crossover pipes and thermostat housing o-rings perish, causing coolant loss and potential overheating. Plastic degrades with heat cycles.
