Driving with fouled plugs risks damaging the catalytic converter, which is an expensive consequence of ignoring the warning sign. Addressing the Source of the Oil To ensure the problem does not recur, a systematic approach to finding the leak is necessary.
Understanding Unburned Fuel Oil on Spark Plugs
Diagnosis and Identification Techniques Identifying oiled spark plugs is a straightforward process that provides immediate insight into the health of the engine. This oil is not supposed to be present in the combustion chamber; its appearance is a physical sign that either the oil is leaking into the chamber or unburned fuel is washing the oil off the cylinder walls during the combustion cycle.
When they fail, oil from the sump can be burned or pushed past the combustion boundary. Accompanying signs of this specific issue include a noticeable check engine light, a pronounced smell of unburned fuel from the exhaust, and a significant decrease in fuel efficiency as raw gas washes past the rings.
