The valve oil seal is one of the important parts of the engine valve group, which is used to seal the valve guide rod and ensure the normal operation of the engine. If the valve oil seal is damaged, it will cause the oil to enter the cylinder along the valve guide rod, resulting in carbon deposit of the spark plug, poor working conditions, and reduced engine power . Therefore, although the valve oil seal is small, its role is critical, once there is a problem, it needs to be dealt with in time
