- In addition to maintaining proper compression, cylinder head gaskets also play a key role in regulating the temperature of the engine. These gaskets are designed to withstand high temperatures and pressures, helping to prevent overheating and potential damage to the engine. Without a functioning cylinder head gasket, the engine could overheat, leading to a range of issues including warped cylinder heads, cracked engine blocks, and even complete engine failure.
- Applications of the 35x47x7 Oil Seal
Once you have selected the most suitable seal available, considering the environment, temperature, shaft speed, pressure, lubrication availability, as well as the size, of course, the seal should be stored adequately and then fitted properly. Here are a few suggestions that could help:-
Wipe the head and block absolutely clean with a cloth moistened with petrol.
- One of the key benefits of using TC oil sealing is its ability to increase the efficiency of machinery by reducing friction and wear. By containing lubricants within the system, TC oil seals help to reduce the amount of energy needed to operate the machinery, ultimately leading to improved performance and a longer lifespan. Additionally, TC oil seals help to protect the internal components of the machinery from contamination, dirt, and debris, which can cause damage and malfunctions.
- Moreover, a worn or damaged valve cover gasket can allow dust and debris to enter the engine, wreaking havoc on sensitive components
The benefits of silicone include:
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.

Pressure - Many oil seals can only withstand low-pressure applications, so understanding the compression set of your components is key.

Put the jack and wooden spacer under the sump and raise the engine just enough to free the supports.

Step-by-step plan for correct installation
There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.

High wear resistance good running properties for general use
There may be a rubber '0' ring oil seal round the base of the distributor, or a paper gasket under the plate of the securing clamp. Remove either seal, clean away all dirt and oil, and fit the new one.
What are Oil Seals?
Refit the sump, taking great care not to disturb the gasket. Hold it up by hand and fit two front bolts and two rear ones to keep it in place while you refit the rest.
