In addition to carbon buildup and oil leakage, black spark plugs can also be caused by overheating. If the engine is running too hot, it can cause the electrodes on the spark plugs to wear down and become coated in carbon deposits. This can lead to poor engine performance and reduced fuel efficiency. It is important to monitor the engine temperature and address any overheating issues promptly to prevent damage to the spark plugs.
When the oil seal material and the chemical are not compatible, there will be a chemical attack, which increases at high temperatures. The only way to remedy this is to select the right material for your application. If you’ll be dealing with harsh chemicals, choose oil seals that are made with reliable materials for their compatibility.
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.



Oil seals come with various lip designs, each serving a unique purpose and suitable for different applications. Let’s discuss the most common industry-standard lip designs:


When selecting valve cover gaskets, head gaskets, and spark plugs, it is essential to prioritize quality, compatibility, and performance. High-quality gaskets and spark plugs are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions and efficient ignition capabilities. Choosing reputable suppliers and manufacturers known for producing high-quality components is crucial to ensure the reliability and longevity of these critical engine components.
Conventional oil seals
Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.
