Water ingress of engine oil is a common fault in the use of internal combustion engine. If the water in the engine oil is not treated in time, it will cause serious consequences. For example, the engine will be scrapped if there are faults such as cylinder scratch and sliding tile. Therefore, to prevent water from entering the engine oil is a problem that must be paid attention to at all times. Since the water inflow of engine oil is a common fault in the use of internal combustion engine, how should we judge the water inflow of engine oil? This article will outline this problem for reference only.
1. If the engine oil contains a large amount of water, the oil level of the engine oil will rise. At this time, we can judge through the oil dipstick. Once the water content in the engine oil is too high, the level of the lubricating oil will exceed the range marked on the dipstick, which is easy to identify.
2. Check whether engine coolant contains engine oil. If some parts of the engine are damaged, the engine coolant will enter the lubrication system. At this time, oil is often found in the coolant. Therefore, checking whether the engine coolant contains engine oil is also a way to check whether the engine oil has water.
3. Carefully observe the appearance state of the engine oil, and you can easily judge whether the engine oil contains water. The oil without water presents a translucent oil bright color, while the lubricating oil containing water presents an opaque brown or earthy yellow. If the oil contains water, the oil will appear milky white with foam after the engine has been running for a period of time. This is due to the chemical reaction between engine oil and coolant under the high temperature inside the engine, and the engine oil will be emulsified into emulsion.
