What are the symptoms of excessive valve clearance in the Geely Emgrand?
1 Answers
Excessive valve clearance in the Geely Emgrand mainly manifests the following symptoms: 1. After starting the engine, there is a continuous crisp abnormal noise, which is most noticeable during cold starts. 2. It causes delayed opening of the intake and exhaust valves, shortening the intake and exhaust time, reducing the valve opening angle, altering the normal valve timing, resulting in insufficient engine intake and incomplete exhaust. This leads to decreased engine power, as well as increased noise from impacts between components in the valve train, accelerating wear. Additional information: The exterior dimensions of the Geely Emgrand are 4544×1832×1671mm, with a wheelbase of 2660mm.
