- Maintenance is another critical aspect of spark plug use
spark plug use. Over time, plugs can become fouled with carbon deposits or damaged by normal wear and tear. Symptoms of misfiring or reduced engine efficiency often indicate the need for inspection or replacement. Regular checks allow for timely intervention, preventing more significant issues down the line.

Oil seal size
Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.
What Is Oil Seal?

Oil seal performance is affected by not only the type and material of the selected oil seal, but also a variety of other factors, such as operating conditions, total eccentricity, rotational speed, the substance to be sealed, and lubrication conditions.
Figure 9 shows items relating to oil seal characteristics.
9 Factors for Selecting Oil Seals
Type ‘C’ oil seal has an additional cup inserted into the outer cup of ‘B’ type. The supplementary metal inner ring provides a superior stiffness. This type is recommended for use in heavy polluted environments. As the static sealing between housing and metallic shell is limited, low viscosity media can “creep”.
Slowly raise the engine about 11 in. (38 mm) and insert wedges between the mounting rubbers and pads .

Oil seals, also known as rotary shaft seals, are designed to prevent oil leaks in rotating machinery by sealing the gap between a rotating shaft and a stationary housing. Proper installation of oil seals is essential to ensure a leak-free performance, which in turn helps to extend the life of the machinery. In this article, we will go over the steps for installing oil seals correctly.
For a more detailed discussion of seal types and type codes, please see the following:
4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.

PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
