It is recommended to stop driving immediately to avoid potential issues. Below are the reasons for water entering the engine oil: 1. Damaged oil cooler: When the cooler pipes crack, external water can seep into the oil cooler, leading to water contamination in the oil. 2. Leaking engine water plugs: After years of use, scaling and corrosion can cause rust on some water plugs, allowing coolant to enter the oil passages from the water channels. This is a common issue, so regular inspection of water plugs is essential. 3. Damaged cylinder liner seals: The seals at the bottom of the cylinders effectively prevent leaks between engine oil and coolant. Over time, these seals endure pressure and corrosion from poor coolant quality, making them prone to failure after prolonged engine operation.
