Under normal circumstances, the main reasons for the oil spill in the following 3 aspects:

Gaskets failed to function

The truck static parts (such as the joint end faces, each end cover, shell gasket, etc.) gasket between components play a role in leakproof. If the manufacturing quality and equipment do not meet technical specifications, it will not be sealed, leak proof, and even accidents. Such as the oil pan or valve cover, because the contact area is large and difficult to compaction, thus forming oil spills.

Loosen all kinds of fastening nuts

Pressure is not too loose gasket leak tight; tight and lead screw around the metal bulge or threaded screw slide caused by oil spill. In addition, the oil pan drain plug if not tighten or loose back scattered, easy to form oil loss, and engine damage burning tile axle.

Aging oil seal failure

A lot of moving parts on the car (such as the North V3 fittings, oil seals, O ring) will be improperly installed, the shaft neck and the oil seal blade are not concentric, sway and throw oil. Some oil seals used for too long, will lose elasticity due to aging of rubber, and found leakage should be updated in a timely manner.

What can prevent the truck from leaking and eliminate hidden dangers?:

First of all, to properly dispose of the North Ben V3 fittings, all kinds of oil pipe joint seal. The union nut of the car is often assembled and disassembled, easy to slip off, and loose, it will cause oil seepage. Replace the union nut, and use the grinding method to deal with its cone seal, so that the nut is pressed and sealed.

Second, to prevent the wheel from throwing oil. North Benz V3 parts wheel bearings and smooth cavity too much grease or oil seal assembly improper, poor quality and aging failure; wheel braking frequently caused by temperature is too high; axle nut loose will cause wheel oil. Therefore, we should use the "cavity smoothing method" (that is, the amount of smooth) dredging vents.

And prevent the one-way valve, vent valve block. As a result, the temperature in the box is increased, and the oil and gas is filled with the whole space, and the discharge is not brought in. The pressure in the box shell is increased, the oil consumption is increased, and the change cycle is shortened. After the engine ventilation system is blocked, the movement resistance of the piston is increased, and the oil consumption is increased. Because of the pressure difference between the inside and outside of the case, it often causes the oil leak in the seal. Therefore, the vehicle should be checked regularly, clear and cleaned.
