- The valve cover gasket is a small but critical component that sits between the valve cover and the cylinder head. Its main function is to prevent oil leaks and ensure that the engine's internal components are properly lubricated. A deteriorating or damaged valve cover gasket can lead to oil leaks, loss of lubrication, and potential engine damage.

Car Head Gasket: Essential Component in Engine Sealing
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.
- Another breakthrough was the integration of artificial intelligence (AI) and machine learning algorithms into spark plug design
e3 22 spark plug. By analyzing vast amounts of data from vehicle sensors and engine performance monitors, these smart spark plugs can adapt to changing conditions in real-time, optimizing ignition timing and fuel delivery for maximum efficiency.
- Moreover, oil seals improve the reliability and safety of motors. Proper lubrication ensures that the motor operates at optimal temperatures, reducing the risk of overheating and potential fires. Furthermore, well-lubricated components are less likely to break down unexpectedly, reducing the likelihood of accidents or equipment failure during critical operations. This is particularly important in industries such as manufacturing, transportation, and power generation, where motors play a crucial role in daily operations.
- In modern engines, head gaskets have evolved to incorporate multi-layer steel designs, improving their durability and resistance to high pressure and temperature. Some even feature advanced materials like copper or mica for enhanced sealing properties. However, despite these advancements, head gaskets remain one of the most common points of failure in an engine, underscoring their vulnerability and the need for careful attention.
Silicone rubber (VMQ)
The maximum allowable shaft speed is a function of the shaft finish, runout, housing bore and shaft concentricity, type of fluid being sealed and the type of oil seal material.
Shaft Speed - Considering the speed that the shaft will be moving, the runout, the housing bore and the type of oil being sealed is vital to making sure you select an oil seal that will not suffer from abrasions or spiralling.

Lubricant can be retained in the space between the main lip and the minor lip.
Metal O.D. wall type Ensures improved fitting retention between the seal O.D. and the housing bore.
How does my engine benefit from high mileage oil?
In addition to its excellent temperature resistance, it is also resistant to ozone, light, and weather conditions. Silicone can be typically found in the food and medical industry as well as in hydraulics and pneumatics. It is often the preferred material for o-rings, moulded parts and flat seals but is also commonly used for electric insulators due to the material’s translucency and flexibility.
VMQ, also known as silicone, is also used for oil seals, but this is less common because the mechanical strength of VMQ is low and this material has poor wear-resistance This makes it less suitable for dynamic applications, but it can withstand fairly low and high temperatures from -60 °C to 200 °C. Many types of VMQ are also suitable for contact with pharmaceutical and food products, so VMQ is an option worth considering. VMQ oil seals are usually available on request.
