top valve cover gasket. The gasket must fit perfectly to execute its sealing duties effectively. Ignoring this replacement can result in the aforementioned issues, turning a minor repair into a major expense.

Oil seals close off the space between stationary and moving components in the mechanical equipment. It saves the lubricant from escaping through the equipment and ensures smooth operation of the machine.
Leather
Recommended for abrasive applications
Good running properties, due to the impregnated seal lip
Can be used on shafts which have a surface roughness outside the range for rubber seals
Not suitable for water

Rotary Wheel Of Auto Parts
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.
PTFE Oil Seals - A relatively new and exciting oil seal, the use of polytetrafluoroethylene means that they can withstand dry or unlubricated operations. With a massive thermal range of -130ºC to +200ºC and a strong resistance to chemicals, they are considered to be the future of rotary shaft seals.

When selecting spark plugs for vehicles, it is essential to consider factors such as compatibility, heat range, electrode design, and material composition. High-quality spark plugs, including iridium spark plugs, are designed to withstand the demanding conditions of automotive operation, providing reliable ignition and combustion. Choosing reputable suppliers and manufacturers known for producing high-quality spark plugs is crucial to ensure the reliability and longevity of these critical components in the vehicle's ignition system.
Shaft surface speed
Put a wood block at least 6 in. (150 mm) square and 1 in. (25 mm) thick as a spacer between the jack and the sump to prevent damage.
• Low-friction torque design
Oil seal specifications
It is quite common for a groove to develop at the sealing lip at some point due to long-term use. As a result, the new oil seal no longer fits and seals properly. It is not strictly necessary to replace or repair the entire shaft. Take a closer look at the dimensions first. It may be possible to fit with a slightly narrower or wider oil seal next to the groove. Alternatively, using the Speedi-Sleeve repair kit, repair the running surface under the seal.
