If the gap is larger than 0.002 in. (0.05 mm) at any point, have the head or block checked and machined flat by a specialist.
In conclusion, valve cover gaskets, head gaskets, and spark plugs are essential components in automotive engines, contributing to the efficiency, performance, and reliability of the engine. Understanding the significance of these components and their proper maintenance and replacement is crucial for optimizing the performance and longevity of the engine.
Oil seals are widely used as sealing devices for machines.
JTEKT's oil seals are described in our catalog, Oil Seals & O-Rings.
However, the catalog uses a large number of technical terms and is very long, so many people seem to have trouble handling it.
Therefore, this series of columns will summarize the following in order:
• The structure, functions, and types of oil seals
• How to select the right oil seal
• Handling of seals, and causes and countermeasures for oil seal failure
When selecting right valve cover gaskets, intake valve cover gaskets, head gaskets, and valve cover gaskets, it is essential to prioritize quality, durability, and compatibility with specific vehicle models. High-quality gaskets are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the vehicle. Choosing reputable suppliers and manufacturers known for producing high-quality gaskets is crucial to ensure the reliability and longevity of these critical components.
The lip is specially designed to ensure the oil seal works effectively with the different forces that arise during rotation. Many different designs and materials are used, so countless types of oil seals are available. These are chosen according to the application; pumps, gearboxes, wheels, and many other rotating applications where fluids need to be sealed. They are used in a variety of sectors, such as the chemical industry, manufacturing, wind turbines, automotive sector, food industry, and more. Oil seals are used in nearly all sectors.
Main Bearing Oil Seal A Critical Component in Engine Performance
Outstanding resistance to mineral oils, aliphatic and aromatic hydrocarbons, as well as CHCs, concentrated and diluted acids, and weak alkalis. Excellent resistance to high temperatures (up to 200 °C) and a low temperature resistance down to -40 °C depending on the type used as well as good mechanical attributes and an exceptionally good ageing resistance make FPM a cut well above the usual synthesis natural rubbers.

Because of the higher temperature resistance of FKM, this material is also chosen for applications where higher speeds play a role, which raise the temperature at the sealing lip considerably. Usually, using FKM will result in a longer life than using NBR. This compensates the higher price of FKM compared to NBR, as an FKM does not have to be replaced as frequently. The low temperature resistance of standard FKM is limited to -15 ˚C.
A valve cover gasket, as the name implies, is a seal located between the engine's valve cover and the cylinder head. Its primary function is to prevent oil leaks from the engine's lubrication system. Over time, due to heat, pressure, and wear, gaskets can deteriorate or crack, leading to oil seeping into areas where it shouldn't be, such as the spark plug wells or combustion chambers. This not only reduces efficiency but can also lead to engine damage if not addressed promptly. Regular inspection and timely replacement of valve cover gaskets are crucial for maintaining optimal engine health.MS
