What are Oil Seals and how do they work?
- The 6.0% 20Valve Cover Gasket, often referred to as the 20 Valve Gasket, is a critical component in the engine of many modern vehicles, particularly those equipped with V8 engines. This gasket plays a vital role in maintaining the proper seal between the valve cover and the engine block, ensuring that oil, coolant, and other essential fluids do not leak out.
- 5. **Clean the valve cover** Use a clean cloth or paper towels to wipe away any dirt, debris, or old gasket residue from the surface of the valve cover. This will help the new gasket adhere better.
In terms of size, oil seals are available in a wide range of dimensions to suit different shaft diameters and housing sizes. It is crucial to select the correct size seal to ensure a proper fit, as using an improperly sized seal can lead to leaks and premature wear.

4. Example of the applications of seals
Due to having a higher density, Viton has the widest temperature range of -40°F to over 400°F (-40°C to over 240°C) making it a perfect choice for higher temperature applications. Viton® also has the largest range of chemical resistance, i.e., it is resistant to silicone oil and grease, mineral/vegetable oil and grease, aliphatic, aromatic, and chlorinated hydrocarbons, non-flammable hydraulic fuels as well methanol fuels, and more.
APPLICATIONS OF OIL SEALS
Conventional oil is the most commonly used type of oil. It is ideal for light-duty, late-model cars with low to average mileage and a simple engine design.

The right valve cover gasket is a critical sealing component that ensures the proper sealing of the valve cover to the cylinder head. This gasket plays a pivotal role in preventing oil leaks and contaminants from entering the engine, contributing to the overall efficiency and reliability of the engine. Selecting the right valve cover gasket is essential for maintaining the integrity and performance of the engine.
