How to judge the valve oil seal is broken, the symptoms of valve oil seal aging
The function of the valve oil seal is to prevent oil from entering the intake and exhaust pipes, to avoid oil loss, to prevent the mixture of gasoline and air and exhaust gas from leaking, and to prevent engine oil from entering the combustion chamber. The valve oil seal is one of the important parts of the engine valve group. Once the gas oil seal is broken, the engine will have malfunction symptoms. Let's take a look at the symptoms of the valve oil seal.
Symptoms of aging or broken valve oil seal
1. The engine burns oil and emits blue smoke.
2. The spark plug has serious carbon deposits and the engine power drops.
3. The decrease of airtightness leads to insufficient Cylinder pressure and engine power decrease.
4. The oil consumption is accelerated, and in severe cases, it will directly cause the engine to burst due to the failure of lubrication and cooling.
Causes of oil leakage of oil seal aging
1. Reasons for assembly: When assembling, if the threads or splines are not aligned, the misplaced Teeth will leak oil due to poor sealing performance, and the oil seal itself will be damaged.
2. Material problem: The tightness of the spring does not meet the process requirements, and if it is too tight, it will cause improper fit of the rotating shaft of the oil seal and abnormal wear. When it is too loose, the pressure will be too small to be compressed, and the sealing effect cannot be achieved.
3. The oil seal and the rotating shaft are not on the same axis, and eccentric wear occurs, causing abnormal wear of the lip.
4. If the lip grease of the oil seal is gone, dry friction will occur, and mechanical wear will quickly grind the teeth.
