1) Seal type
Check the faces of the head and block for flatness. Alloy heads in particular can distort and then leak.
Choosing Quality Industrial Oil Seals
Nitrile (NBR) Oil Seals

The oil seal should be tough enough to withstand the pressure and the vibrations caused by the shaft and bore. Check if the oil seal is strong enough to tolerate the pressure and vibration.
Silicone oil seals, which are also called VMQ, have strong resistance to temperature, which ranges from -140 degrees Fahrenheit to 392 degrees Fahrenheit. They are also resistant to ozone, light, and harsh weather conditions. Silicone is frequently used in hydraulics and pneumatics, as well as in the food and medical industries. Due to the material’s transparency and flexibility, it’s commonly chosen for the manufacturing of o-rings, molded parts, and flat seals, as well as electrical insulators.

Auto parts oil seals play a crucial role in the proper functioning and maintenance of vehicle systems. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the integrity and efficiency of various components within the vehicle. From wheel hub oil seals to steering oil seals, these components are essential for the smooth operation and longevity of automotive systems.
NBR, also known as nitrile rubber or nitrile, is the most popular material for an oil seal because of its good resistance to many oils and greases, such as mineral grease and hydraulic oil. Depending on their composition, synthetic oils and greases, such as those based on glycol, can damage NBR rubber materials. Depending on the amount of glycol, a PTFE lip seal may be the best choice. NBR is also unable to cope with contact with acids and solvents. The rubber is suitable for oil and grease at temperatures from -35 °C to 100 °C.
