The use of cars，often occur in oil leaks，It will directly affect the technical performance of the car，Cause lubricating oil、waste of fuel，Consumption power，Affecting car Rong neat，Cause environmental pollution。Due to oil leak、A decrease in lubricating oil inside the machine，Lead of poor lubrication、Cooling insufficient，It will cause early damage to the mechanical parts，Even left an accident hidden danger。

1. The main cause of oil leakage in common vehicles

1、Product (accessories) Quality、The material or process is not good; the structural design is problematic。

2、Pretend to be high -speed improper，With the surface unclean，Cushion damage、Shift or fail to install it in accordance with the specifications of operating procedures。

3、Tastebar twisting force、Slip Degreed or Looshe and fall off, resulting in failure。

4、Earnation in the long -term use of sealing materials，aging deterioration、Deformation failure。

5. Add too much lubricant, excessive oil surface, or add wrong oil.

6、Parts (Cover Class、thin wall parts) Joint surface flexion deformation、Damage of the shell，Make lubricating oil out。

7、ventilation plugs、After the unidirectional valve is blocked，Due to the effect of air pressure difference in the box shell，often causes oil leakage。

2. Prevention of vehicle oil leakage measures

1. Pay attention to the pad.

Auto static location (such as the Seabetjoint surface of each junction、Dove each end、Shell、Cushion、Plane enamel cover plate, etc.) The pads between the components play a leak -proof sealing effect。If the material、Production quality and installation does not meet technical specifications，No sealing and leak -proof effect is not available，Even an accident。If the oil bottom shell or the valve cover，Due to the large contact area, it is not easy to compact，As a result, oil leakage。Pay attention to putting properly when disassembling，Check carefully，And assembled according to specifications。

2、All types of tight nuts on the car need to be tightened according to the prescribed torque。

Overproof pressure pads will leak; too tight will make the metal around the screw holes raised or twist the filament to cause oil。Another，Oil bottom shell placing oil stuffing if it is not tightened or returned to loose，It is easy to cause oil loss，Then the "burning tile holding shaft" machine loss accident。

3. Replace the failure oil seal in time.

Many dynamic sites on the car (such as oil seal、O -type circles) will not be installed，Blame and oil seal blade different heart，Polying and shaking oil。Some oil sealing will lose elasticity due to the aging of rubber for a long time。Discovery leak should be updated in time。

4、The use of automobile parts will produce a daily wear limit (such as piston and cylinder, etc.)

As a result, the indoor high -pressure gas in the burning room enters the crankshaft box，and forced the oil to leak outside。Therefore，When the exhaust gas is severely challenged at the cover of the oil mouth，Should be maintained or replaced early。

5. Avoid blocking the unidirectional valve and ventilation valve.

As a result, the temperature in the box shell increases，Oil and gas is full of space、Can Lifting River cannot be discharged，increase the pressure consumption of lubricating oil in the seabet iobox shell to increase the consumption of lubricating oil and the replacement cycle。After the engine ventilation system is blocked，Added the motor resistance of the piston，Increase fuel consumption。Due to the effect of air pressure difference in the box shell，often causes oil leakage。Therefore, it is necessary to check the vehicle regularly、Dredging、Cleaning。

6. Properly solve the sealing of various types of oil pipes.

Automotive pipe tube nuts often disassembled，Easy to slide on the filament and loosen;，The central line of the two cone faces does not coincide with poor contact;，As a result, it will cause oil leakage。Replace the joint tube nut，Use the grinding method to solve its cone sealing，Press the nut and solve the seal。

7. Avoid the wheels from shaking oil.

Too much lubricating oil in the wheel bearing and cavity，or the oil sealing assembly is inappropriate，Poor quality and aging failure; the temperature of the wheels caused by frequent braking;。Therefore, the "empty cavity lubrication method"，Dredging ventilation，Strict selection of high -quality accessories，and assemble and high -speed in accordance with the process specifications。

3. Maintenance and maintenance points for vehicles

Pretend to be under extremely clean conditions，parts of the parts without bumps、No scratches、Bond and other attachment; strict operating regulations，Sealing parts should be installed correctly，Prevents not in place to be deformable; master the performance specifications and requirements of the sealing parts，Replace the disorders in time;，Use sheet metal cold for correction; a shaft hole parts that are easily worn can use metal spray plating、Welding repair、Adhesive、Mechanical processing and other processes to reach the original size; try to use sealing glue，If necessary, you can use paint to achieve the ideal sealing effect; seabet loginnut slide buckle、Loosteen should be repaired or replaced with new pieces，Turn to the specified torque; check the appearance quality carefully before assembly of rubber sealing;，Avoid knocking deformation; add lubricating oil according to regulations，Regular cleaning and dredging the ventilation holes and one -way valve。As long as the above points are achieved，The problem of the oil leakage of the vehicle is completely cured。
