Is Volkswagen's Oil Burning Problem Serious?
1 Answers
Volkswagen engines burning oil is caused by issues with internal engine components, which is a relatively serious problem. Valve Stem Seals: The valves are essentially designed to prevent oil from leaking into the combustion chamber. However, over time, they can become worn or aged. Severe cases can affect the valve's sealing performance, making oil burning very likely to occur. Excessive Piston Clearance: When a car has been in use for an extended period, incomplete combustion can lead to carbon deposits adhering to the piston rings. If not cleaned for a long time, this can cause the gap between the piston rings and the cylinder wall to widen, allowing oil to flow into the combustion chamber and resulting in oil burning. In severe cases, it can even lead to engine seizure.
