The HVAC equipment HS code mappingoil seepage problem of the engine oil sap needs to be investigated in time. The oil seepage problem of the engine oil sap is one of the common problems in automobile maintenance, especially in old vehicles. Although it can be well maintained,In order to maintain the competitiveness of cost, some car manufacturers' bottom shell sealing is not very good. Therefore, many car owners will encounter such problems, which not only affect the performance and fuel consumption of the car, but also the safety. Therefore, it is very necessary to investigate and deal with the problem of oil seepage of the engine oil sap in a timely manner. What is the engine oil surne seepage? The engine oil surr is the bottommost cover of the engine. This lid is usually made of aluminum and has a gasket attached. Car manufacturers usually make this part as light as possible to reduce the weight and cost of the vehicle. At the position where the cover and the engine body are connected, there is usually a gasket to achieve sealing. If the gasket is aging or damaged, it may cause oil leakage. In addition, if the engine performs poorly or the engine has ever failed, it may also affect the sealing.The reason for the poor sealing of the engine bottom shell - the gasket is aging or damaged: the gasket is usually made of Vitalon or other rubber materials. With the increase of the age of the car, the gasket will slowly harden, crack and expand and bulge, which will lead to oil leakage. - Use low-quality parts: If low-quality gaskets, gaskets or fastening bolts are used when replacing the gasket, oil seepage of the oil span may occur. - Normal wear: due to the vibration of the car Dynamic, thermal expansion and engine operation, the oil pan will slowly wear out and loosen. This will cause the gasket to lose its tightness and oil leakage. - Over-tightening: Although the idea of over-tightening the cover is attractive in some cases, over-tightening of the oil supp will cause the torque to be uneven, so that the gasket is not sealed and the engine oil begins to leak.The harm of poor sealing of the engine bottom shell - damage to the transmission shaft: oil leakage from the oil supp may affect the transmission shaft and make it lack lubricating oil. This may cause noise in the drive shaft, so it needs to be replaced. - Power loss: If the engine bottom shell keeps leaking oil, it will lead to insufficient engine power. This is because insufficient lubricating oil will reduce the performance and acceleration of the engine. - Reduced fuel efficiency: Oil spillage in the oil san may lead to a decrease in fuel efficiency. If the bottom shell is saturated with oil, it is impossible to lubricate the engine and mechanical movement, which will make your car more difficult to start and more fuel-consuming. How to solve the problem of poor sealing of the engine bottom shell - replace the gasket: For cases where the problem is relatively minor, replacing the gasket can solve the problem of oil leakage very well. This is one of the cheapest and fastest ways, butIt should be noted that in order to avoid the recurrence of this problem, high-quality gaskets should be used, and assembly skills are also required. If possible, it is recommended to replace the oil sp, that is, replace it with a new fuel tank to avoid oil leakage. - Repair the oil sp: Due to the design defects of some oil sp itself, it may need to be repaired. Generally, a layer of sealant is applied to the surface of the oil pan to make up for the problem of oil leakage caused by its imperfect sealing. Although repairing the oil span can solve the problem, it is usually not the best solution. - Replacing the oil sp: For more serious oil leakage problems, replacing the oil span is better than repairing the oil sp. In general, it is recommended to replace it with a new fuel tank to avoid oil leakage, because its degree of damage and sealing do not meet the standards of use. Before replacing, it is also necessary to check whether other parts such as oil filters need to be replaced. After the first few subsequent drives, you need to check and determine whether there is oil leakage.Conclusion The oil seepage problem of the engine oil sap shell needs to be investigated in time. Because oil leakage may lead to a decline in the performance of the driven vehicle, increase fuel consumption, and even safety hazards. Regular maintenance of the car is an effective measure to reduce the impact of engine bottom oil leakage. Timely inspection and troubleshooting of oil leakage can help you avoid unnecessary trouble. More importantly, the correct installation and selection of high-quality car-level fast Yiwu auto parts replacement parts can help you prevent such problems from happening again.
