How to quickly determine whether the valve oil seal is leaking oil?

There are many reasons for the rapid loss of engine oil and the occurrence of oil leakage. One of the most common engine oil leakage is valve oil seal problems and piston ring problems. How to determine whether the piston ring is wrong or the valve oil seal is wrong, you can judge by the following two simple methods:

1. Measure cylinder pressure

If it is a piston ring problem, determine the amount of wear through the cylinder pressure data, if it is not quite serious, or a cylinder problem, by adding a repair agent, it should be automatically repaired after 1500 kilometers.

2, see whether the exhaust port has blue smoke

Blue smoke is the phenomenon of burning oil, mainly caused by piston, piston ring, cylinder liner, valve oil seal, valve duct wear, but first to eliminate the exhaust pipe caused by the burning oil phenomenon, that is, the oil-water separator and PVC valve damage will also cause burning oil.

To determine whether the valve oil seal oil leakage, you can use the method of fuel door and throttle to judge, fuel door exhaust pipe blue smoke is the piston, piston ring and cylinder liner wear clearance is too large; Blue smoke from loose throttle exhaust pipe causes valve oil seal damage and valve duct wear.

3, the consequences of valve oil seal oil leakage

The valve oil seal oil leakage will burn in the combustion chamber because the valve oil seal seal is not tight and the oil leaks into the combustion chamber, and the exhaust gas will generally appear like blue smoke;

If the valve continues for a long time, it is easy to produce carbon accumulation, resulting in the reverse valve closing is not strict, and the combustion is not sufficient;

At the same time, it will cause carbon accumulation in the combustion chamber and the fuel nozzle or blockage of the three-way catalytic converter;

It will also cause the engine power decline and fuel consumption to increase significantly, and the related parts are damaged, especially the spark plug condition has decreased significantly.

It can be seen that the consequences are still very serious, so replace the valve oil seal as soon as possible.
