While this does not fix the underlying mechanical failure, it can reduce the rate at which oil enters the combustion chamber, extending the time between replacements and minimizing smoke output. Accompanying this is a distinct smell of burning oil and a noticeable loss of power, as the engine struggles to generate the necessary force with one or more cylinders offline.
Recognizing the Symptoms and Causes of Oil on Spark Plugs
Symptom Likely Cause Severity Blue/gray exhaust smoke Burning oil Moderate to Severe. Recognizing the Symptoms Beyond the Visual While the visual cue of a shiny, black, oily residue is the most obvious sign, the operational symptoms tell a more immediate story.
Understanding the Mechanism of Contamination The fundamental design of a spark plug creates a narrow gap between its center and ground electrode, a gap that must remain clear for a strong spark to jump. This condition is rarely random; it is a diagnostic clue that reveals specific problems within the cylinders, ranging from worn piston rings to incorrect oil viscosity.
Recognizing the Symptoms Beyond the Visual
Preventing Future Occurrences For those who must drive a vehicle with high mileage, using a higher viscosity oil can sometimes help mitigate the symptoms. Primary Causes of Oil Fouling The presence of oil is almost always a symptom of an internal leak.
