Analysis of Oil Leakage in Engine Diesel Filter
Damaged filter housing
The filter edge is damaged and leaks air
The outer sealing ring of the filter is cracked, aged, and permanently deformed
The pressure resistance of the filter base plate or housing does not meet the standard, and the base plate protrudes within the required pressure
The screw teeth are not compatible, and the filter is washed off
The filter does not have a bypass valve, and it has been used for too long or there are many impurities in the oil. Failure to replace the filter paper in a timely manner can cause blockage and oil leakage
The blockage in the car's oil circuit causes excessive pressure, resulting in damage to the filter
Before driving at low temperatures, if the car is not warmed up, the oil flow may be poor, the pressure may be high, or inferior oil may be used, resulting in clogging of the filter paper. If the driver's license suddenly accelerates, it will cause excessive fuel pressure and damage the filter
When the pressure limiting valve on the oil circuit is set too high, the oil filter paper is blocked, and there is no safety valve set, it leads to excessive oil pressure and damage to the oil filter
