This condition leads to misfires, reduced fuel efficiency, increased emissions, and potential damage to the catalytic converter due to unburned fuel entering the exhaust system. The Dangers of Oil Fouling Oil on a spark plug is a symptom of a condition known as fouling, where the electrode is coated in a substance that prevents arcing.
Identifying and Fixing Oil Fouled Spark Plugs
Similarly, a valve cover inspection can identify leaking valve stem seals. Unlike components such as bearings or shafts, spark plugs do not experience mechanical friction that requires lubrication.
If oil is present, simply cleaning the plug is a temporary fix; the root cause, such as worn rings or seals, must be addressed to prevent the problem from recurring. Identifying Oil Fouling Diagnosing oil-fouled spark plugs is straightforward.
Proper Steps for Diagnosing and Fixing Oil-Fouled Spark Plugs
When oil coats the spark plug, it creates a conductive path that drains the ignition coil's energy, resulting in a weak or missing spark. This is distinct from carbon fouling, which appears as a dry, black soot.
