Engine Oil Seal:
A shaft’s surface finishing will determine how effective the sealing will be. The spiral lead and the direction of the finish tool marks have an impact on the sealing effectiveness. Therefore, it’s imperative to ensure that the shaft surface finishing is maintained.


Car engine oil seals are essential components that prevent oil leaks and maintain proper lubrication within the engine. They play a crucial role in preserving the integrity and efficiency of the engine, contributing to its overall performance and longevity. High-quality engine oil seals are designed to withstand the demanding conditions of automotive operation, ensuring reliable sealing solutions for critical engine components.


Friction modifiers: Friction modifiers help reduce friction when your engine is operating under high temperatures and with heavy loads. This additive can also help you maximize your fuel efficiency.
When the bore and shaft centers are misaligned, seal life will be shortened because the wear will be concentrated on one side of the sealing lip.

When replacing spark plugs, it is important to follow the manufacturer's recommendations for the correct type and gap setting. Using the wrong spark plugs can lead to engine misfires and poor performance. Additionally, it is essential to properly torque the spark plugs to prevent damage to the cylinder head.
