- The importance of using the right type of spark plug cannot be overstated. Different engines require specific heat ranges, electrode types, and thread sizes. Using the incorrect plug can lead to pre-ignition, where the air-fuel mixture ignites before the piston reaches top dead center, causing engine knocking and potential damage. It can also result in increased fuel consumption and higher emissions, contradicting modern efforts towards environmental sustainability.
In addition to preventing oil leakage, the piston oil seal also helps to reduce friction between the piston and the cylinder wall. This is important for maximizing engine efficiency and prolonging the life of the engine components. By reducing friction, the seal helps to improve fuel economy and reduce wear and tear on the engine.

Step-by-step plan for correct installation

Cassette seals are designed to maximise grease or oil retention and protection against liquid or solid contaminants. These seals are provided with their own bushings in which dirt is kept out and oil/grease kept in by a multi-lip seal.
Unthinkable in the list of seals are oil seals, which provide a seal against splashing oil. The most important oil seals are used for rotating shafts and valve stem seals. Oil seals are intentionally never completely sealed to lubricate the seals and prevent wear.
