Additional value of accessories, using screws and gaskets to prevent oil leakage

In the course of daily use, vehicles often leak oil. Vehicle oil leakage not only causes waste of lubricating oil and fuel, but also directly affects the technical performance of the vehicle. The most important thing is that summer is approaching, vehicle oil leakage and high temperature weather may cause important safety accidents.

Fan Liangyin, a vehicle maintenance technician, said that clever use of nuts and gaskets can prevent vehicle oil leakage.

　　Due to vehicle oil leakage, the internal lubricating oil of the machine is reduced, resulting in poor lubrication and insufficient cooling of auto parts, causing early damage to the machine parts, and even leaving hidden accidents. Vehicle oil leakage is usually due to poor quality, material or craftsmanship of auto parts, and structural design problems.

　　Fan Liangyin said that some automobile oil leaks are also caused by improper assembly of parts, unclean parts, damaged gaskets, displacement, etc., as well as excessive wear of the sealing material after long-term use, aging and deterioration leading to deformation and failure. In addition, after the vent plug and the one-way valve are blocked, due to the pressure difference between the inside and outside of the case, oil leakage will often occur at the weak seal.

　　Some oil seals will lose their elasticity due to rubber aging if they are used for too long. Any leakage should be updated in time. Fan Liangyin told the author that to prevent vehicle oil leakage, car owners should always check the nuts. All kinds of fastening nuts on the car must be tightened according to the specified torque. If the nut is too loose, the gasket will leak; too tight will cause the metal around the screw hole to protrude Start or twist the thread to cause oil leakage. At the same time, car owners need to pay attention to the gasket between the parts of the car at rest to play a leak-proof and sealing role.

　　 In addition, car owners need to avoid blocking check valves and vent valves. After the engine ventilation system is blocked, the movement resistance of the piston is increased and fuel consumption is increased. Due to the difference in air pressure between the inside and outside of the case, it often causes oil leakage at the weak seal. Therefore, regular inspections, dredging, and cleaning of vehicles are required.
