How to Deal with Engine Oil Spraying from the Exhaust Pipe?

[DiFinn]

If the ventilation valve is aged, the only solution is to replace it, as the ventilation valve is itself a wear-prone component. It is normal for the ventilation valve to develop issues after the vehicle has been driven for a certain mileage. If the pistons, cylinder liners, or piston rings are excessively worn, replacing the corresponding components can also resolve the issue. Regular oil changes should be performed to minimize engine wear. The reasons for sudden large amounts of engine oil spraying from the exhaust pipe are as follows: 1. The crankshaft ventilation valve has aged. 2. Excessive wear of the pistons, cylinder liners, or piston rings: This can cause the engine to lose its original sealing performance, allowing engine oil to easily enter the cylinder and subsequently be expelled with the exhaust gases from the exhaust pipe. Finally, severe wear between the valve stem and valve guide can lead to oil moving up and down, which can also cause similar phenomena to occur.
