oil in sparkplugs

I tried to change my sparkplugs today. I pull out the second sparkplug I noticed there is oil. Can you guy tell me what is wrong? Is my head gasket leak?

thank you

If theres oil on the plug you probably have bad piston rings and you need to get that checked . the easiest thing to do is have someone pull teh codes to find out exactly wat is wrong

well is it oil on the tip? As in oil inside the cylinder, or is there just oil on the white part of the plug? Big difference. If its in the cylinder (on the part of the plug that actually fires) then it could be a number of serious problems. However if it is just down that tube where the spark plug wire and spark plug connect and on the white part of the plug then it is a cheap fix. In this case its just four little ring washers you get from the dealer for $2.00 each and then pull off the valve cover to replace them.
