Black smoke from the vehicle's exhaust pipe; 4. Unstable idle or stalling at idle; 5. Flashing check engine light; 6. Burning of engine oil; 7. Increased fuel consumption. The causes of exhaust valve damage are: 1. Quality issues with the exhaust gas recirculation system itself; 2. Improper maintenance; 3. Issues with fuel quality; 4. Aging of the exhaust valve. The function of the exhaust valve is to appropriately reduce fuel consumption, improve engine efficiency, lower exhaust temperature, and reduce the generation of nitrogen oxide compounds and carbon monoxide.
