Oil seals are commonly used in engines, gearboxes, and other rotating machinery to prevent the leakage of oil from shafts and bearings. They are typically made from rubber or elastomeric materials that are resistant to oil and heat. The seal is installed in a housing or bore that is larger than the shaft, and it is pressed against the shaft to create a tight seal.
- Advancements in spark plug technology have further enhanced their utility. Iridium plugs, for instance, offer longer lifespans and improved performance due to their superior conductivity and resistance to wear. This innovation not only reduces maintenance intervals but also contributes to overall engine efficiency and vehicle longevity.
- A valve cover gasket, whether it's at the front or rear, serves as a barrier, maintaining the integrity of the engine's oil system. It seals the space where the valves, rocker arms, and pushrods operate, keeping oil from seeping out and contaminants from creeping in. The rear valve cover gasket, specifically, is situated behind the cylinder head, typically in engines with overhead valves or camshafts.
Oil leak: the most frequent failure of the oil seal

Even though it’s better than other materials in terms of toughness and wear time, it is preferably used in dry-running applications. The salient demerit of this material is its cost.
