How to Deal with Water Contamination in Engine Oil?
1 Answers
When water contaminates the engine oil, it is necessary to completely drain the old oil and replace it with new oil. Below are the specific reasons for water contamination in engine oil: 1. Damage to the oil cooler can cause water to enter the oil. If the cooler's pipes crack, external water can seep into the oil cooler, leading to water contamination in the oil. 2. Leaking engine water plugs can result in water entering the oil. After several years of engine use, corrosion from scale can cause some water plugs to rust through, allowing coolant to flow from the water passages into the oil passages and down into the oil pan. Regular inspection of water plugs is essential. 3. Damage to the cylinder liner sealing rings can lead to water contamination in the oil. Wet cylinder liners are in direct contact with coolant, and the lower sealing rings on the liners effectively prevent leakage of oil and coolant. Over time, these sealing rings endure pressure and can be corroded by poor-quality coolant, leading to failure after prolonged engine operation. 4. Cracks in the cylinder liner can easily cause water to enter the oil. When a heated cylinder liner is in direct contact with coolant, cracks can form. Once cracks appear, coolant can directly enter the cylinder and seep into the oil pan through the cylinder walls, turning the oil white. This whitening of the oil can lead to poor engine combustion, white smoke emissions, and other issues. 5. Damage to the cylinder head gasket can result in water contamination in the oil. The cylinder head gasket seals each cylinder, as well as the corresponding coolant and oil passages, preventing water from entering the oil. If the gasket is damaged and the coolant circulates rapidly, water from the coolant passages can flow into the oil passages, causing water contamination in the oil.
