What Are the Causes of Increased Diesel Engine Oil?
1 Answers
Specific reasons are introduced as follows: 1. Water entering the engine oil (or coolant): This is usually due to damage to the cylinder gasket or water plug (for vehicles with an oil cooler, it could also be damage to the oil cooler). 2. Diesel fuel entering the engine oil: This is typically caused by internal leakage in the fuel injector or fuel pump. 3. Overfilling of engine oil: This is usually due to insufficient inspection during oil changes. If the oil pressure is significantly lower than before, it indicates diesel fuel entering the oil, either through the fuel injector (where the injector fails to function properly, allowing fuel to flow down the cylinder wall into the oil pan) or due to damage to the sealing rings of the high-pressure pump or hand fuel pump. Additional Information: If there are sand holes or cracks in the cooling water cavity of the cylinder block or cylinder head, cooling water can enter the oil pan. When the 'engine oil' in the oil pan increases, timely and appropriate measures should be taken. Otherwise, the dilution and degradation of the 'engine oil' can make it difficult to form a lubricating oil film on moving parts such as the crankshaft and bearings, leading to severe mechanical failures like 'bearing seizure' or 'crankshaft seizure.'
