What to Do If Water Gets into the Engine Oil?
1 Answers
If water gets into the engine oil, it is necessary to drain all the oil and replace it with new oil. The main causes of water entering the engine oil are as follows: 1. Damage to the oil cooler causing water to enter the oil: If the pipes of the oil cooler break, external water can seep into the oil cooler, leading to water contamination in the oil. 2. Leakage from the engine water plug causing water to enter the oil: After several years of engine use, corrosion from scale can cause some water plugs to rust through, allowing coolant to enter the oil passages and drain into the oil pan. 3. Damage to the cylinder liner seal causing water to enter the oil: A damaged cylinder liner seal is a major cause of water entering the oil. Therefore, when diagnosing the cause of water in the oil, always check the condition of the cylinder liner seal. 4. Cracks in the cylinder liner leading to water entering the oil: When a heated cylinder liner comes into direct contact with coolant, cracks can form. Once cracks appear, coolant can enter the cylinder directly and seep into the oil pan through the cylinder walls, causing the oil to turn milky. This can result in poor engine combustion, white smoke, and other issues. 5. Damage to the cylinder head gasket causing water to enter the oil: If the cylinder head gasket is damaged and the coolant circulation is fast, water from the coolant passages can flow into the oil passages, contaminating the oil.
