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. 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.

When it does, it follows the path of least resistance and accumulates on the porcelain insulator and metal shell of the plug. This intrusion physically blocks the spark, preventing the ignition of the air-fuel mixture and effectively turning the cylinder into a non-combustion chamber.
Oil on spark plugs is a common yet often misunderstood symptom that points directly to the health of an engine’s internal combustion process. If valve stem seals are the issue, a relatively affordable valve seal replacement can resolve the oil on spark plugs issue.

If these rings fail to seal properly, oil from the sump can creep past them and into the combustion chamber, a condition known as "blow-by. Low compression in one or two adjacent cylinders strongly suggests failed piston rings, while a drop in pressure when the throttle is snapped closed points to worn valve seals.
