- In conclusion, black spark plugs are a common issue that can be caused by a variety of factors, including a rich air-fuel mixture, oil leaks, and ignition system problems. Regular maintenance and inspection of spark plugs are essential for keeping the engine running smoothly and efficiently. By addressing black spark plugs promptly, you can prevent more serious problems down the road and ensure that your vehicle continues to perform at its best.

What should you take into account when selecting an oil seal? Different types of oil seals and various types of materials are available, each designed for specific uses. It is also important to select the right size of oil seal for the best results. For this reason, selecting the right oil seal requires adequate understanding of the application in which it will be used.

In addition to their longevity, iridium spark plugs also provide improved fuel efficiency and overall engine performance. The consistent and powerful spark produced by iridium spark plugs helps to optimize combustion in the engine, leading to better fuel economy and smoother acceleration. This can result in savings at the gas pump and a more enjoyable driving experience for car owners.

Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.
These are comparable to type R and RST, except the outer case does not have a metal reinforcement ring. To compensate, the outside is not made of normal rubber, but a hard, heavy-duty rubber fabric. The advantage is that these types can be made in a split version. They are almost always produced to order, and made of NBR or FKM.
