In conclusion, engine oil seals, power steering oil seals, and motor oil seals are essential components in automotive systems, contributing to the efficiency, performance, and reliability of the vehicle. Understanding the significance of these seals and their proper maintenance is crucial for optimizing the performance and longevity of the vehicle.
- The dimensions specified in its name—12x22x5—are not arbitrary; they reflect the seal's diameter, height, and thickness, respectively. These measurements must be exact to guarantee a snug fit within the housing it is designed to protect. The 12mm diameter signifies a compact size, ideal for smaller mechanisms where space is at a premium. The 22mm height suggests that this seal is robust enough to withstand a reasonable amount of pressure without failing. Finally, the 5mm thickness ensures that the seal has enough substance to create a reliable barrier against both the outward flow of oil and the ingress of foreign particles.

Free the cover by levering gently round the edge with a screwdriver; take care not to bend the flange.
Oil seals are one of the major contact type sealing devices.
• They prevent leakage of the lubricant or other sealed substance, and
• prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside.
If the drive gear has slanting teeth, they may cause the rotor arm to turn. If it does, mark its new position to aid refitting

305 valve cover gaskets. These gaskets are easy to install and can be done at home with the right tools and instructions.

Head Gasket and Valve Cover Gasket: Ensuring Engine Integrity
Rubber valve cover gaskets are crucial components in automotive engines, serving to create a secure seal between the valve cover and the cylinder head. These gaskets prevent oil leaks and contaminants from entering the engine, ensuring proper lubrication and protection of critical components. High-quality rubber valve cover gaskets are essential for maintaining the integrity and performance of the engine, contributing to optimal engine operation and reliability.
