Auto engine valve Manufacturer shares with you.

First, the most common oil leakage is the problem of valve oil seals and piston rings. How to determine whether it is a piston ring problem or a valve oil seal problem can be determined by the following two simple methods:

1.Measure cylinder pressure

If it is the piston ring that determines the amount of wear from the cylinder pressure data, if it is not very serious, or through additives, it should be automatically repaired after 1500 kilometers.

2. Look for the blue smoke in the exhaust port

Blue smoke is a phenomenon that burns oil. It is mainly caused by pistons, piston rings, cylinder liners, valve oil seals, and wear. Can cause burning oil. In order to determine whether the valve oil seal is leaking oil, you can judge it by the way of the throttle and loose throttle. The exhaust port of the gas valve is that the piston, piston ring and cylinder liner are worn too much.

Second, the consequences of valve oil seal leakage

The valve oil seal oil will burn in the combustion chamber. If the valve oil seal does not penetrate into the engine oil tightly, the exhaust gas will show blue smoke. If carbon deposits are easily generated for a long time, the valve will not be closed properly. Insufficient combustion. It can also lead to the accumulation of carbon in the combustion chamber and the nozzle or blockage of the three-way catalyst; it can also cause the engine power to drop and the fuel consumption to increase significantly, and related equipment to be damaged, especially the working conditions of the spark plug. You can see that the consequences are still serious, so you should replace the new valve oil seal as soon as possible.
