The relationship between vehicle oil leakage and sealing

Common causes of oil leakage in vehicles 2. Improper assembly, unclean mating surfaces of parts and components, damaged gaskets, displacement or failure to install according to operating procedures. 3. Uneven tightening force of the tightening nut, wire breakage or looseness falling off, etc. lead to work failure. 4. The sealing material wears excessively after long-term use, aging and deterioration, and deformation fails. 5. Too much lubricating oil is added, the oil level is too high or the wrong fuel is added. 6. The joint surface of parts (side covers, thin-walled parts) is flexed and deformed, the casing is damaged, and the lubricating oil seeps out. 7. After the vent plug and one-way valve are blocked, due to the difference of air pressure inside and outside the casing, oil leakage is often caused at the weak seal. Measures to prevent oil leakage in vehicles Pay attention to the role of gaskets The gaskets between the parts in the static parts of the car play a leak-proof sealing role. If the material, production quality and installation do not meet the technical specifications, the sealing and leak-proof effect will not be achieved, and even accidents will occur. Such as oil pan or valve cover, due to the large contact area, it is not easy to compact, resulting in oil leakage. All kinds of tightening nuts on the car must be tightened according to the specified torque. If the gasket is too loose and not tightened, the gasket will leak; if it is too tight, the metal around the screw hole will bulge or the thread will be slipped, causing oil leakage. Timely replace many parts (such as oil seals, O-rings) on the vehicle with failed oil seals, which will throw off oil due to improper installation, misalignment between the journal and the edge of the oil seal, and deflection. Some oil seals will lose elasticity due to rubber aging if used for a long time. If leaks are found, they should be updated in a timely manner. Avoid blocking the one-way valve and the ventilation valve, which will cause the temperature in the casing to rise, and the oil and gas will fill the entire space and cannot be discharged, which will increase the pressure in the casing, increase the consumption of lubricating oil and shorten the replacement cycle. After the engine ventilation system is blocked, the movement resistance of the piston is increased, which increases the fuel consumption. Due to the difference of air pressure inside and outside the casing, oil leakage is often caused at the weak seal. Therefore, regular inspections, dredging and cleaning of vehicles are required. Properly solve the problem of frequent disassembly and assembly of various types of oil pipe joint sealing vehicle union nuts, which are easy to break and loosen, causing oil leakage. Replace the union nut, use the grinding method to solve the conical surface seal, and compress the nut to solve the seal. Avoid wheel hub oil throwing Too much lubricating oil in the hub bearing and cavity, or improper oil packaging, poor quality and aging failure, excessive hub temperature caused by frequent braking, loose axle nuts, etc., will cause wheel hub oil throwing. Therefore use“Cavity lubrication method (i.e. proper amount lubrication)”, to clear the ventilation holes. https://www.orksealing.com/
