Worn or damaged piston rings: Piston rings are responsible for sealing the combustion chamber and preventing oil from escaping into the cylinder.
Poor engine design: Some engine designs are prone to oil burning due to inherent engineering flaws, such as inadequate oil drainage or poor piston ring design.
Excessive engine blow-by: Blow-by refers to the leakage of combustion gases and pressure from the combustion chamber past the piston rings and into the crankcase. Excessive blow-by can cause the oil to be pushed into the combustion chamber, leading to oil burning.
Faulty Positive Crankcase Ventilation (PCV) system: PCV system aims to recycle blow-by gases and regulate crankcase pressure. A faulty or clogged PCV system can result in excessive crankcase pressure, forcing oil into the combustion chamber.
Oil leaks: If the engine has oil leaks, such as a faulty gasket or damaged seal, it can lead to oil loss and subsequent burning when the engine is turned on.
