Under the action of the skeleton oil seal, the rigidity of the oil film just makes the oil film and the air contact end form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; if the thickness is too small, dry friction may occur, causing the oil seal and shaft to wear; if there is no oil film between the sealing lip and the shaft, it is easy to cause heat and wear. . Therefore, when installing, it is necessary to apply some oil on the sealing ring, and at the same time ensure that the skeleton oil seal is perpendicular to the axis line. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also lead to excessive sealing of the lip. wear. During operation, the lubricant in the casing seeps out a little, so that it is ideal to form an oil film on the sealing surface.
- One of the main considerations when replacing spark plugs is the cost. The cost of new spark plugs can vary depending on the type and brand you choose. On average, a set of four spark plugs can cost anywhere from $20 to $100. It's important to keep in mind that the cost of labor for installation may also need to be factored in if you're not comfortable replacing the spark plugs yourself.
- Single Lip, No Spring: This lip design, which does not include a spring, is mainly used for sealing a non-pressure medium, such as grease, or protecting against dirt.
- The material used in oil seals is also important, as it affects the seal's durability and resistance to chemicals and heat

If the car has a manual gearbox , select first or reverse gear and put the handbrake full on. Otherwise, disconnect the battery and remove the starter motor .
Aspects to consider when selecting oil seals
Check the faces of the head and block for flatness. Alloy heads in particular can distort and then leak.
Material Code ISO 1629
Oil seals are used in any industrial application that has a rotating or moving part assembly. This includes:
One of the key advantages of the 30-50-10 oil seal is its ability to provide a tight seal without compromising on flexibility. This means that the oil seal can effectively prevent oil leaks while allowing for smooth movement of the machinery or equipment it is installed in.

Preparing to replace the sump gasket

c15 valve cover gasket. If dirt or debris were to enter the engine, it could cause damage to sensitive components such as the valves and camshafts. By maintaining a tight seal with the valve cover gasket, you can keep your engine clean and free from contaminants.

If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.


Box: If a BX appears at the end of the part number, that oil seal will be in a box.
