What are the effects of water in engine oil on the engine?

[VioletAnn]

Water in engine oil can cause the engine temperature to rise excessively in mild cases, and in severe cases, it can lead to faults such as cylinder scoring and bearing seizure. In the worst scenarios, it may even result in engine failure. The causes of these effects and their solutions are as follows: Causes of the effects: Under the high temperature inside the engine, the oil undergoes a chemical reaction with the coolant, causing the oil to emulsify. This significantly reduces the lubricating properties of the oil. Inorganic acids: When the antioxidant properties of the oil deteriorate, the organic acids generated by oil oxidation react with water to form inorganic acids. These acidic substances can corrode engine components, leading to rust or damage. Solutions: Check if the cylinder liner seals are aged and replace them promptly. Inspect the engine for water blockages and replace the radiator or cylinder gasket as necessary.
