Here is another problem associated with engine oil overfilling:
One severe problem would be creating what is called a “RUN-A-WAY” diesel.
This occurs when the oil level would be high enough that the crank and connecting rods would splash in the oil in the oilpan.
This splashing can create an oil mist or vapor that can be drawn into the cylinders on the intake stroke, around the piston rings or other paths, creating an unregulated fuel source for the engine.
A diesel engine’s speed is regulated by the amount of fuel injected into the combustion chamber, with the unregulated supply, the engine will rev out of control until it blows up from centrifugal forces.
The safest thing to do is, "RUN-A-WAY".
