Understanding these problems is essential for owners and potential buyers alike. Below are some of the most common issues associated with this engine.

Common Issues Reported

1. Oil Consumption: One of the most frequently reported problems is excessive oil consumption.

-Increased Repair Costs: Early detection and resolution of engine issues can save owners from costly repairs down the line. Delaying maintenance can exacerbate problems and lead to more extensive damage.

-Decreased Resale Value: A vehicle with a history of engine problems may have a lower resale value. Prospective buyers are often wary of purchasing vehicles that have documented issues.
