It depends on whether the oil is on the outside or inside electrode of the spark plug. Inside the cylinder, oil deposits on the electrodes mean engine wear. But on the external porcelain insulator (white in color), it means your valve cover gaskets are leaking into the spark plug well or you spilled oil on the white insulator when you were filling the engine oil.

Actually most of the time I find oil on the sparkplugs and no other complaints is because your valve cover is leaking down into the hole that your sparkplug is in, some sparkplugs sit deap in the head and have an Oring around them to stop the oil, that oring leaks or plastic valve cover is warped causing oil to get on plug, when you pull plug out, its very oily but you didnt have a running problem, a running problem with oil on plug would be as the others suggested

People stop with the piston rings. The olny oil from the rings is the little thats pumped threw the rod to help lube the cylinder. any ecessive oil has to be comming from bad valve seals or a leaking head gasket.

most likely worn piston rings, allowing oil to leak up into the cylinders and get on the spark plugs.

Almost 100% sure it's piston rings, or scratches in the cylinder wall. The reason for the rings is to keep oil from being sucked up into the firing chamber from the crankcase . If they are worn, they will let oil through. Same thing if the cylinder walls are damaged.

All of them?? Could be bad valve seals or bad oil rings if it's all. If just one is burning oil, it would probably be the head gasket.

Most likely the piston rings.

could be a clogged air cleaner or worn valve guides or a possible broken ring!
