Will a Damaged Exhaust Valve Cause Oil Leakage in a Car?

[SanKaden]

A damaged exhaust valve can cause oil leakage in a car. Symptoms of a damaged exhaust valve: When the exhaust valve remains constantly open, the car may exhibit symptoms such as emitting black smoke, experiencing poor acceleration, and increased fuel consumption. When the exhaust valve remains constantly closed, it can affect the car's exhaust emissions, potentially causing the vehicle to fail annual inspections. Consequences of a damaged exhaust valve: It becomes impossible to control the amount of exhaust gas recirculation. Excessive exhaust gas participating in recirculation can affect the ignition and performance of the air-fuel mixture, thereby impacting the engine's power output. It can lead to the car burning engine oil, resulting in severe blue smoke from the exhaust. Additionally, it loses the oil-gas separation function, causing the engine to draw in oil along with air during the intake process.
