The role of oil pan pad in automobile
The main function of the oil pan pad is to seal the crankcase, prevent oil leakage, provide stable support for the engine, and reduce oil fluctuations caused by vibration .
The oil pan pad, located under the engine, can be removed and installed and is usually stamped from thin steel plates, or cast in cast iron or aluminum alloy for complex shapes. Its internal design has an oil stabilizer baffle to prevent the diesel engine from shaking and splashing the oil surface during turbulence, which is helpful to the precipitation of impurities in the lubricating oil .
The material of oil pan pad and its advantages and disadvantages
CORK : This is the earliest oil pan cushion material used in the history of automobiles. The production process is simple, but due to the shape limitation, the sealing effect is not good, and it is easy to leak or even explode. This material has been eliminated in the European and American markets, but some of it is still used in China.
RUBBER : It is very popular in foreign countries, mainly used for gearbox sealing. The materials can be subdivided into NBR and ACM, showing good matching diversity. However, due to the technical limitations of the Chinese market, the acceptance of this material is not high .
PAPER gasket : it is a relatively new oil pan gasket material on the market, with stable performance, good sealing effect and plane sealing characteristics. This material is often used in the valve body pad of multi-wave box. At present, such products mainly rely on imports .
hard rubber mat material (MODULE RUBER) : composed of metal framework and rubber outsourcing, has excellent stability and firmness. This material is widely used in the American market, and many new automobile gearboxes use it for sealing .
O-ring material : recently began to be used in oil pan pad, the popular models are 6HP19 and 6HP26. This material has high machining accuracy requirements and relatively high maintenance costs .
Replacement interval and maintenance suggestions
In the absence of damage, the oil pan pad generally does not need to be replaced frequently. Vehicles usually need to be replaced when the fuel level is low through the monitoring system. When selecting oil pan pad, pay attention to material and practicality, avoid using cheap ones to prevent oil leakage after installation .

Material and historical evolution of oil pan gasket
The material of oil pan gasket has undergone many changes. The early use of cork material, although the production process is simple, but the sealing effect is limited, and easy to leak or even explosion, this material has been eliminated in the European and American markets, but in China there are still some use .
Rubber material is very popular in foreign countries, mainly used for transmission sealing, but in the Chinese market due to technical restrictions .
Paper gasket material is a recent innovation to provide stability and excellent sealing, commonly found in multi-wave box body gasket . The modular rubber pad, with its combination of metal skeleton and rubber outsourcing, leads the development trend of oil pan pad, especially in the American market . In addition, the O-ring material has also begun to be applied to the oil pan pad, although the processing accuracy is high, but its sealing performance is excellent .
Replacement interval and maintenance suggestions
Under normal circumstances, if there is no obvious damage, the oil pan gasket generally does not need to be replaced frequently. Vehicles usually need to be replaced when the fuel level is low through the monitoring system. When selecting the oil pan gasket, we should pay attention to the material and practicality, and avoid using cheap products to ensure the normal operation of the engine and avoid oil leakage caused by gasket problems .
