Why is my spark plug covered in soot?
Black, dry soot on the electrodes and insulator tip indicates a carbon-fouled plug. This can be caused by a dirty air filter, excessive driving at low speeds, too rich of a fuel/air mixture or idling your vehicle for too long.
What causes excessive oil on spark plugs?
As a general rule, oil on spark plugs can be caused by bad valve cover gaskets, worn spark plug o-rings or valve guides, a faulty head gasket or a broken piston ring. Most of the time it can be caused by a leaking valve cover or bad spark plug o-ring that can easily be replaced.
Can a bad coil pack cause a Kia Rio to stop running?
Bad Coil Packs are one of the more problematic ignition issues that can occur with the Kia Rio. A bad oil pack can make your Rio almost un-drivable. Or it may have little effect at all on the engine’s ability to run. It’ll get worse as they lose their ability to fire the spark plugs.
What do I need to replace spark plugs on Kia Rio?
The tools needed to complete this procedure include a 10mm socket with a 1/4″ drive ratchet, a 5/8″ spark plug socket, an extension bar, a 3/8″ drive ratchet, a spark plug gap gauge and a tube of dielectric grease.

Therefore, when this component is faulty, it paves a way for oil to pass through the valves and leak into the spark plugs. A clear sign that points to leaking O-ring seals as the reason for oil on spark plug threads is engine misfiring.
What to do when your spark plug Wells fill with oil?
Although the leak can sometimes be fixed by tightening the valve cover bolts, more often than not the valve cover gasket and well seals will need to be replaced. If this leak is left untreated, the spark plug boot could swell, which in turn will lead to a misfire in the engine. It’s import to fix this leak as soon as you discover it.
