Detailed explanation of Mercedes Benz oil seal leakage: from causes to countermeasures

Mercedes Benz oil seal leakage:

Reason for oil leakage:

The sealing components are aging, affected by high temperature, high pressure, and chemical erosion, and the rubber oil seal is aging and losing elasticity.

Improper installation, unclean surface, inaccurate positioning, and poor sealing.

Engine abnormality, high temperature and high load operation, faulty impact on oil seal.

Crankcase ventilation failure, pressure rise causing oil seal leakage.

The quality of the oil seal is poor, and non original or inferior products are prone to oil leakage.

Oil leakage hazard:

Affects performance, oil leakage leads to insufficient lubrication and cooling of components, resulting in reduced power efficiency.

Causing malfunctions, long-term failure can lead to serious problems such as engine overheating and cylinder pulling.

Pollute the environment, oil droplets contaminate the ground, and dirty the chassis compartment.

There are hidden dangers, and there is a risk of fire when in contact with high-temperature components, driving or slipping.

Detection method: Check for oil stains on the appearance, observe the color of exhaust gas, check the oil level, and use ultraviolet fluorescent agent to find oil leakage points.

Solution: Replace the oil seal, select the appropriate accessories for correct installation, repair the installation surface, inspect the ventilation system, address engine malfunctions, and perform regular maintenance.
