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.
Will engine light come on if oil is overfilled?

This foamy texture of the oil acts like a bad lubricant, and the oil is not pumped effectively.
How do I know if I have an overfill problem?
There are other indicators that will suggest you have an overfill problem, including blue exhaust smoke, a burning smell, an oil leak, or a high reading on your oil pressure gauge (if equipped).
