In the use of the vehicle, often there will be oil leakage, it will directly affect the technical performance of the car, resulting in a waste oil, fuel, and power consumption, affecting the car clean and tidy, causing environmental pollution. Because oil spills, reduce internal engine oil, resulting in poor mechanical lubrication, cooling deficiency, can cause early mechanical damage, even leaving accidents.

A common vehicle of the main reasons oil spill

1. poor quality products, materials or workmanship; structural design problems.

2. High speed improper assembly, with the dirty surface, the liner breakage, displacement or failure to install procedures specification.

3. The fastening nut uneven force, or the slide fastener Songkuang yarn break off as a result of failure of the work.

4. The sealing material wear and tear after prolonged use overrunning, aging deterioration, deformation failure.

5. Lubricants add too much oil level is too high or a mistake of oil.

6. The component engagement surface deflection, breakage of the housing, the lubricating oil leaking.

7. The vent plug, the check valve plug, since the pressure difference inside and outside the enclosure effect, often lead to a weakness in the seal leakage.

Second, oil spill prevention measures vehicle

1. emphasis on cushioning effect. Spacer portions between the auto parts play left leakproof seal. If the material is installed on the production and quality does not meet the technical specifications, it would not achieve the effect of leak-proof seal, or even an accident. The oil pan or a valve cover, due to large contact area easily compacted, thereby causing leakage.

2. all kinds of car nuts are tightened regulations required tightening torque. Pressure is not too loose will leak tight gasket; tight turn around the screw will be threaded metal or projections effort caused by oil spills. In addition, the oil pan drain plug if not tighten or back off loose, likely to cause loss of engine oil, engine damage accident "bush-burning axle" in ensue.

3. timely replacement of oil seal failure. Many movable parts of the car due to improper installation set, journal and seal edge misalignment, yaw and oil slinger. Some seals used for a long time due to rubber aging and loss of elasticity. Found leakage should be updated.

4. Avoid check valve, vent valve blocked. Tank shell thereby causing temperature rise, the entire space filled with oil, is not discharged out of the tank shell increased oil consumption and increased pressure replacement cycles. After the engine breather system is blocked, increased resistance to movement of the piston, so that increase in fuel consumption. Since the pressure difference inside and outside the enclosure effect, often lead to a weakness in the seal leakage. Hence the need to carry out regular inspection of the vehicle, and clear, clean.

The proper settlement of all kinds of pipe joints sealed. Regular car attaching and detaching the union nut, while the fastener easy to slip loose broken wire can cause oil leakage. Replace the union nut, sealing solution which is tapered grinding the nut seal pressing solved.

6. Avoid oil slinger wheel. Excessive wheel bearings and grease cavity, wrong assembly or seal, poor quality and aging failure; frequent wheel brake due to the high temperatures; axle nut loosening can cause oil slinger wheel. Therefore, use the "cavity lubrication", and clear the vent.
