How to Deal with Increased Engine Oil in Diesel Engines?

[DiSarah]

Diesel engine oil increase can be addressed as follows: 1. Check if water in the oil is causing the increase. If the increase is due to water and the engine is not damaged, replace the leaking parts, clean the water tank, and replace with clean lubricant and antifreeze. 2. Inspect the fuel injectors. Preliminary judgment can be made based on the engine exhaust smoke color and whether power is reduced. Alternatively, stop the cylinders at idle speed to identify if a particular injector is malfunctioning. If a faulty injector is found, remove it and send it to a test pump for testing and repair. 3. Examine the diesel pump. When the plunger in the diesel pump loses pressure, diesel may leak from the plunger. Typically, plungers experience some wear during use. If not repaired promptly, oil leakage can occur, necessitating immediate inspection and repair at a 4S shop.
