- The consequences of a blown head gasket can be severe
- The cost of installation should also be considered
- Car engine oil seal is a crucial component in any vehicle's engine system. It plays a vital role in preventing oil leaks and maintaining proper lubrication of the engine components. In this article, we will discuss the importance of car engine oil seals, their functions, and the consequences of a failing oil seal.
Remove the radiator (See How to remove a car radiator ) if necessary, to make room for removing the crankshaft pulley.

3. Check for damage before installing seals
Oil seals have a flexible lip that actually rubs against the rotating shaft or housing to prevent leakage. The spring keeps the lip in contact with the shaft. Bearing isolator oil seals are dynamic seals that incorporate a rotor or rotating member and a stator or stationary member. The rotor actually turns with the shaft. Some oil shafts are bearing isolators with a labyrinth construction. Others incorporate simpler O-rings.
No matter the PTFE machining techniques and other processes used in making mechanical parts, they tend to fail due to some reasons. The same thing applies to oil seals. When they are exposed to some factors, they fail. The factors are stated below alongside the solutions.
Unscrew the pulley bolt anticlockwise with a socket and bar. Start it turning with a sharp blow on the bar.

Areas of application of this rubber are suggested by its outstanding temperature resistance (-55 °C to +200 °C), although this must not be applied to hot water or steam. Although silicone rubber almost matches NBR in oil resistance, it does not match the latter's physical and mechanical properties.
Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
Wear and oil loss remains two of the most frequent signs of engine seal failure and, if not paid attention to, it can give rise to a breakdown in the vehicle’s system. Regular maintenance and routine oil changes minimize the issues associated with oil seals and potential oil loss.
Lubricant can be retained in the space between the main lip and the minor lip.
Extrusion and Nibbling
Lubricants applied between moving and stationary elements of mechanical equipment help to prevent damage. But when the equipment are under high pressure, the lubricants tend to escape, hence the need for oil seals to prevent the clashing of dry parts. Practically all mechanical equipment, including car engines, assembly machines, and PTFE machined parts use these oil seals to prevent harmful interaction that can result in damaged parts.

It is generally used in the union of two lubricated parts, so that it hermetically seals both sides. Therefore, it guarantees the proper engine operation and helps to maintain the vehicle’s distribution system in better condition.
