Over time, unburned fuel and carbon buildup can foul additional plugs, and the excess oil entering the combustion chamber leads to carbon accumulation that damages the catalytic converter, an expensive component to replace. Worn or broken piston rings or damaged cylinder walls allow oil from the crankcase to migrate into the combustion chamber, a condition known as "blow-by.
