Why do diesel engines always leak engine oil

Why do diesel engines always leak oil? Here is a fault analysis for you.

Carry out maintenance on diesel generator sets

1. Check whether the type, quantity and quality of the engine oil meet the requirements.

Second, whether the mating surfaces of various parts of the diesel engine are smooth and flat, and whether the processing dimensions meet the requirements. The sand-casting parts and die-casting parts should be free of sand holes and air holes. Check whether all kinds of paper gaskets, sealing strings, oil seals and screws meet the requirements and are tightened.

Iii. Whether the lubrication of the diesel engine is unobstructed and meets the requirements (the oil return hole of the follower column of the air-cooled diesel engine is very important.)

Fourth, for diesel engines without negative pressure, it is also necessary to check whether the breathing is unobstructed and meets the requirements, and whether there is air leakage in the cylinder into the crankshaft, causing oil spraying or leakage.

Five, the temperature of the diesel generator set should not be too high, and the cooling and heat dissipation performance should be good.
