Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.

Refit the rocker or cam cover, aligning its fixing holes with those on the head. Check that the gasket edge aligns with the cover flange all round, and is not distorted. If necessary, adjust it gently with tweezers or long-nosed pliers. Tighten bolts evenly to just compress the gasket.

Failure to install oil seals correctly can lead to failure. Factors such as knocking the seal into place may cause its spring to tilt in the bore or be out of alignment. Consider switching to a solid adhesive and applying it around the surface of the spring to prevent it from loosening.
One way to identify a seal that has not been fitted correctly is to check the rough shear of the rubber. To resolve this issue, align the mounting tool before positioning the seal in place.

Silicone rubber (VMQ)

ERIKS type R (type A according to the DIN standard) is identical in shape to type M, but has a rubber outer case with metal reinforcement on the inside. The rubber creates a good seal in the housing, even if the housing has suffered minor damage or is not in its best condition for other reasons. The RST version has a dust lip. These types are often chosen to replace a type with a metal outer case because they are easier to install and can cope with minor damage to the groove, such as scratches.

When it comes to choosing new spark plugs for your car, it is important to consider both cost and quality. While cheaper spark plugs may seem like a more cost-effective option upfront, they may end up costing you more in the long run if they need to be replaced more frequently. Investing in high-quality spark plugs made of premium materials can help improve your car's performance and fuel efficiency, ultimately saving you money in the long term.

Oil seals are protective elements. They prevent the mixing of water and lubricants within a machine, thereby ensuring optimal machine functionality. Also, oil seals help to prevent lubricant leakage at high pressure like when the machine is working at an extremely high rate. Not only that, radial shaft seals stop foreign components from entering a machine. This is because they can contaminate the lubricant and even damage the machine.

Also known as a Rotary Shaft Seal, Shaft Seal, Lip Seal, Elastomeric Lip Seal or any variation of these. It is a simple device for excluding dust, dirt, water or any other contaminant whilst retaining lubricant in rotary shaft equipment. Generally, it has been developed as a means of protecting the bearings of rotating shafts.

Most oil seals consist of some basic elements that configure their structure, such as the sealing element, the metal case, and the spring:
