What are the reasons for engine oil spraying from the exhaust pipe?

[LaDominic]

Engine oil spraying from the exhaust pipe is caused by: 1. Cylinder blow-by; 2. Clogged or damaged crankcase breather; 3. Excessive crankcase pressure; 4. Oil retention in the cylinder, resulting in temporary oil discharge; 5. Worn turbocharger floating bearing seals. The function of an engine is to convert the thermal energy of gasoline into mechanical energy by burning it in a sealed cylinder to expand gases and push the piston to perform work. Engine maintenance items include: 1. Regularly changing engine oil and oil filter; 2. Maintaining good crankcase ventilation; 3. Regularly cleaning the crankcase; 4. Periodically cleaning the fuel system; 5. Routine maintenance of the radiator; 6. Fuel system maintenance and cleaning.
