This is because in the working process of the diesel engine oil pressure higher than the pressure, so that the oil through the core of the cooler part of the damage leakage into the cooling water. When the engine stops rotating, due to cooling water pressure is higher than the oil pressure, resulting in cooling water through the core damaged parts into to the bottom of the oil casing.
