What are the consequences of overfilling engine oil?
1 Answers
Consequences of overfilling engine oil: 1. Causes blue smoke from the engine exhaust pipe, which means burning oil; 2. May lead to piston ring seizure, fuel injector clogging, and other faults. Excessive oil can be forced into the combustion chamber and burned, forming carbon deposits on the piston rings, piston tops, valve seats, and fuel injectors, resulting in wear between the piston and cylinder; 3. Excessively high oil levels can generate oil mist when agitated by the connecting rod big end, which may ignite upon encountering high temperatures, causing crankcase explosions; 4. Too much oil increases the pressure in the lubrication system, making oil seals prone to damage and leading to oil leaks.
