Car oil leakage is a situation we often see, but it is a scene that every rider doesn’t want to see. Usually, because the car’s oil leakage means a serious precursor to car breakdown, the cool car has nothing to worry about. Tell you how to prevent car leaks?
Seven Measures to Prevent Vehicle Oil Leakage Solving the Biggest Trouble First: Pay attention to the role of cushions.
The gaskets between the parts where the vehicle rests (such as the joint end faces, the end caps, the housing, the cover mat, the plane cover plate, etc.) play a role in preventing leakage. If the material, production quality and installation do not meet the technical specifications, it will not achieve sealing leakage, even accidents. Such as the oil pan or valve cover, due to the large contact area and difficult to compact, resulting in oil spills. When disassembling, pay attention to proper placement, carefully inspect and assemble according to specifications.
Second: All kinds of fastening nuts on the vehicle must be tightened according to the specified torque.
If the pressure is too tight, the gasket will leak; if it is too tight, it will cause the metal around the screw hole to bulge or screw the screw to cause oil leakage. In addition, if the oil drain plug of the oil pan is not tightened or loosened, it will easily cause the loss of oil, and then the machine damage of “burning and holding the shaft†will occur.
Third: Replace the failed oil seal in time.
Many moving parts on the car (such as oil seals, O-rings) will be improperly installed, the journals and the oil seal edge are not the same, and the oil will be thrown off. Some oil seals used for too long will lose the flexibility of the canal due to aging rubber. Found that leakage should be updated.
Fourth: Parts replacement cycle.
If the auto parts are used too long, there will be excessive wear (such as pistons and cylinders), which will cause the high-pressure gas in the combustion chamber to enter the crankcase and force the oil to leak out. Therefore, when the outer cover of the oil filler cover is severe, wear parts should be repaired or replaced as soon as possible.
Fifth: Avoid check valve, vent valve blocked.
As a result, the temperature in the enclosure rises, oil and gas fill the entire space, and no canal is discharged. As a result, the pressure in the enclosure increases and the consumption of lubricant oil increases and the replacement cycle shortens. After the engine ventilation system is blocked, the piston's movement resistance is increased and the fuel consumption is increased. Due to the pressure difference between the inside and outside of the enclosure, it often causes oil leakage in the weak sealing area. Therefore, vehicles need to be regularly inspected, dredged and cleaned.
Sixth: Properly solve all types of oil pipe joint seals.
The joint nut of the vehicle is often disassembled and disassembled, and the slide wire is easily broken and loose; the accuracy of the two joints' bell mouth is poor, the center line of the two cones is not coincident and the contact is bad; the taper is different but not consistent, which will cause oil leakage. . Replace the union nut, use a grinding method to solve the cone seal, make the nut tight and solve the seal.
Seventh: Avoid wheel throwing oil.
Wheel hub bearings and cavity too much lubricating oil, or its oil packaging with inappropriate, poor quality and aging failure; brakes frequently caused by the hub temperature is too high; axle nut loose, etc. will cause the hub to throw oil. Therefore, "cavity lubrication method (that is, appropriate amount of lubrication)" is used to clear the ventilation holes, and high-quality accessories are strictly selected, and assembly and high speed are performed according to the process specification.
