How to judge diesel burning tile

If a diesel engine suddenly hears a "why, where" noise in the crankcase during work, it sounds like a sound produced by drilling a large drill bit on a hard steel piece in the absence of lubricating oil. It is a precursor to the lack of oil and burning tiles. When this sound occurs, it should be stopped and checked. Usually when the following three conditions occur at the same time, it can be judged that the bearing of the diesel engine is burned: the temperature of the engine oil rises sharply above 90°C. The oil pressure was normal and suddenly dropped sharply. A large number of bearing alloy chips were found when the oil filter was disconnected or the oil pan was cleaned.
