The hydrodynamic ribsa) have a two-stepped rib configuration provided in one direction on the air face of the lip. Even if the first rib is worn out, the second rib comes into contact with the shaft surface, meaning that this type of oil seal ensures higher sealing performance. Seal with Side Lip A large side lip ensures prevention of entry of dust/water.
ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).
Oil seals close spaces between moving or stationary mechanical components to prevent lubricants like grease and oil from escaping, while also preventing dust, dirt, moisture, and other contaminants from entering the seal. Also known as shaft seals, dirt seals, lip seals, or grease seals, the primary components of any oil seal include an inner metal ring, which provides structural support, and a spring, which provides interference for effective sealing.
In conclusion, cylinder head gaskets are a critical component of a vehicle's engine, playing a key role in maintaining proper compression and regulating engine temperature. Regular inspection and maintenance of these gaskets are essential to ensure the continued performance and longevity of the engine. By taking care of this important component, vehicle owners can avoid potentially costly repairs and keep their engines running smoothly for years to come.Notes

Antioxidants: Antioxidant additives work to slow oxidation and the forming of deposits in motor oil. They also help keep the engine clean and extend the life of the motor oil.
After the oil seal has been installed, check for leaks. You can do this by applying pressure to the system and observing for any signs of a leak, such as fluid escaping from the area where the oil seal is installed. If a leak is present, you may need to remove the oil seal and start the installation process again.
Iridium spark plugs are the most advanced and expensive type of spark plug. They offer the best performance and longevity, with some models capable of lasting up to 100,000 miles. Iridium spark plugs have a very small electrode, which allows for a more precise spark and improved engine performance. They are recommended for high-performance vehicles and those with turbocharged engines
Thoroughly clean the sleeve at the back of the pulley, and look for any roughness on it where it touches the seal. If necessary, smooth it with fine wet-and-dry abrasive paper.
