The car engine will work flawlessly if all its parts are carefully lubricated with high-quality oil. To do this, motorists periodically replace the substance in the crankcase. To avoid the spread of oil to other parts and assemblies, all connecting elements are sealed with special seals and rings.

The functional principle of crankcase breather seal

After some time, the ABAKUS brand Seal, crankcase breather cease to fulfill their function and need to be replaced with new consumables. When the system is depressurized, the oil will begin to "leave", a significant expense item will be added due to the need for constant topping up of lubricants. In addition to additional expenses for oil, there is a high probability of particles of seals getting into the engine. This is already fraught with engine failure. The rubber-sealing ring, being in an aggressive oil environment and under the constant influence of high temperatures, quickly becomes unusable. It is very important to monitor its condition and change it in time.
