Engine Overview and Common Failures

The most common complaints are failures in traction due to turbine valve or EGR contamination. Coolant leaks often occur due to a cracked cooling tee. Additionally, the lower flange of the PCV tube occasionally ruptures, causing oil leakage into the oil pan. On high mileage, valve seats can burn out, resulting in loss of engine compression. If the serpentine belt snaps, it can get caught in the timing system, leading to catastrophic engine failure.
