[HannahMarie]

The reasons for oil spray from the exhaust pipe of a single-cylinder diesel engine are: 1. Worn piston rings causing poor sealing; 2. Damaged cylinder gasket in certain areas. The methods to address oil spray from the exhaust pipe are: Check if the breather pipe is clear, and clean or replace it if necessary. Precautions for exhaust pipe maintenance include: 1. Close the choke when starting the engine in cold winter weather and open it promptly after the engine warms up; 2. Avoid installing windshields or decorative items in front of the engine and muffler; 3. Do not drive for long periods at high load in low gear; 4. Avoid revving the engine at high RPM while stationary for extended periods; 5. Clean the muffler surface promptly when it accumulates excessive dirt or mud; 6. Ensure the muffler gasket is properly installed and tightly secured to prevent air leaks during installation.
