What is the situation with oil spraying from the exhaust pipe?

[McElizabeth]

The reasons for oil spraying from the exhaust pipe are: 1. Poor quality diesel with excessive impurities; 2. Excessive wear of the fuel injector, leading to poor atomization; 3. Changes in the valve timing of the diesel engine, resulting in valve clearance deviation; 4. The diesel engine operating at too low a water temperature. The solutions for oil spraying from the exhaust pipe are: 1. Check the oil level using the dipstick or dashboard; 2. Inspect the water vapor and replace the corresponding parts; 3. After confirming the fuel injector is qualified, replace the diesel and adjust the engine valve clearance. The exhaust pipe is part of the engine exhaust system, which mainly includes the exhaust manifold, exhaust pipe, and muffler.
