Single - Replacing the crankshaft oil seal is a relatively simple process, but it is important to ensure that the replacement seal is installed correctly to prevent any future issues. To replace the crankshaft oil seal, the engine must be drained of oil, the crankshaft pulley must be removed, and the old seal must be carefully pried out of its housing. The new seal can then be installed using a seal driver tool to ensure that it is properly seated in the housing.
- Another important feature of silicone rubber gaskets is their flexibility
- This comprehensive guide will provide you with an overview of oil seal dimensions, including their importance, common types, and how to measure them. By the end of this article, you will have a solid understanding of oil seal dimensions and how to apply this knowledge in real-world scenarios.
- The head gasket, as its name suggests, sits between the engine block and cylinder head, serving as a seal that prevents the mixing of coolant, oil, and combustion gases. It's a critical barrier, maintaining the integrity of the engine's cooling and lubrication systems while also facilitating compression within the cylinders.

- Applications of Molded Gaskets
- Replacing a damaged head gasket can be a complex and costly procedure, often involving the complete disassembly of the engine. Symptoms of a failing head gasket include coolant loss, oil contamination, white smoke from the exhaust, and engine overheating Symptoms of a failing head gasket include coolant loss, oil contamination, white smoke from the exhaust, and engine overheating

auto head gasket. Regular maintenance, including checking for coolant leaks and ensuring proper oil levels, can help prevent such issues.

5. Sealing the grease container when not in use reduces the risk of contamination.
Standard Sealing Lip Designs
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.


If these specific tools aren’t available, it’s entirely possible to correctly seat an oil seal in its housing using a hammer. Ideally, this hammer will be plastic or rubber due to it’s more forgiving nature. Using this and a strike plate that covers the entire seal will lend you accuracy while driving it in. The downside to this method is the inability to drive the seal any further than the strike plate will allow.
