Can you damage an engine by overfilling with oil?
Engine damage – Too much lubricant in the system can cause pressure on the crankshaft to increase. This can result in oil entering the crankshaft exhaust pipe, running through into the combustion chamber, blocking the suction hose with oil soot and potentially leading to engine overload.

What happens when you overfill the oil pan?
The oil pan can hold a little excess oil, so exceeding the max line by a few millimeters or overfilling by half a quart of oil should be fine. Fluid expansion may happen during hot temperatures, so the engine is designed to accommodate it.
