If it was stuck to the cover, smear gasket sealant along the cover flange and upper gasket and leave it to dry for a few minutes.
One of the key features of Mico spark plugs is their advanced technology, which allows for better ignition and combustion. This leads to smoother engine operation and enhanced fuel efficiency, ultimately saving you money on fuel costs. Additionally, Mico spark plugs are engineered to resist fouling and corrosion, ensuring consistent performance over time.

Variety of Oil Seals
Regular maintenance and inspection of the 25x47x7 oil seal are also important in preserving its performance over time. By checking for signs of wear or damage and replacing the seal as needed, machine operators can ensure that the seal continues to provide reliable protection against oil leaks.
Lubricant Amount - Seals will always perform best when lubricated, however in some machines there are more likely to be dry spells. For these cases, selecting a leather or PTFE seal will be beneficial, as both can operate with less lubrication than others.

Waterproof rubber gaskets are designed to provide a secure and watertight seal, making them ideal for applications where protection against moisture and environmental elements is essential. These gaskets are commonly used in outdoor equipment, marine applications, and electrical enclosures to prevent water ingress and ensure the integrity of the sealed components. The waterproof properties of rubber gaskets contribute to the reliability and longevity of the sealed systems.
The cost of new spark plugs can range from as low as $2 to as high as $20 per plug. Cheaper spark plugs are often made of basic materials and may not last as long as more expensive options. On the other hand, high-quality spark plugs are made of premium materials such as platinum or iridium, which can resist wear and corrosion better than cheaper materials.

Valve cover gaskets and head gaskets are essential components in automotive engines, serving distinct yet crucial roles in maintaining the integrity and functionality of the engine. The valve cover gasket seals the junction between the valve cover and the cylinder head, preventing oil leaks and contaminants from entering the engine. On the other hand, the head gasket seals the cylinder head to the engine block, ensuring the containment of combustion gases and the separation of oil and coolant passages.
1. Clean the Surface
ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.
J: Additional code is added here as an identifier when two or more seals have exactly the same type codes and dimensional numbers.
It is important to regularly inspect and replace worn-out piston oil seals to ensure the proper functioning of the engine. This can help to prevent costly repairs and extend the life of the engine.
