Most commonly, this occurs when valve cover gaskets degrade, allowing oil to leak down the spark plug tubes and into the porcelain ceramic. The oil creates a low-resistance path for the spark energy, causing the ignition coil to overheat and fail.

A proper diagnostic involves a compression test and a leak-down test to determine whether the rings or the valves are the source of the pressure loss. This contamination disrupts the spark necessary for ignition, leading to misfires, rough idling, and a noticeable drop in fuel economy.
Identifying the source of the oil is the critical first step, as it points to internal engine wear or a failed seal. Preventive Measures and Maintenance Regular oil changes with the manufacturer-recommended viscosity can extend the life of valve seals and rings.

Another frequent culprit is a failing head gasket, which can force coolant and oil mixtures into the cylinder deck, coating the plugs. Restoring Ignition Function Simply cleaning the plugs is a temporary fix; the underlying leak must be addressed to resolve the issue permanently.
