Today, traditional oil seals have to compete with a new variant oil seal, which is used in most modern engines.
- Furthermore, the spark plug's advanced gap configuration allows for a stronger spark, leading to better combustion and increased power output. This translates into a more exhilarating ride experience, as the SSR 125 motorcycle accelerates swiftly and smoothly, all thanks to the precision ignition provided by the spark plug.

- Moreover, a compromised valve cover gasket can allow debris and moisture to enter the engine, leading to corrosion or even engine failure in extreme cases

The sealing process involves the interaction between the rotating shaft and the elastomeric material, resulting in a dynamic barrier that prevents fluid leakage and maintains system integrity.
Figure 5 explains the JTEKT seal numbering system.
Seal numbers consist of
(1) the seal type code,
(2) the spring code,
(3) the lip type code,
(4) the dimensional numbers, and
(5) the special type code,
and Table 6 shows examples of each of these codes/numbers.
1. The structure of the oil seal is simple and easy to manufacture. Simple oil seals can be molded once. Even the most complex oil seals are not complicated to manufacture. Metal frame oil seals can also be composed of metal and rubber required oil seals only by stamping, bonding, inlaying, molding and other processes.
Fit the new gasket to the cover or head — whichever the old gasket was fixed to.

Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.
