I changed the spark plugs and wires today and two of the plugs were coated in oil. Any ideas on what would cause this? gaskets, seals?
 
was it on the top of the plug? or the side of the plug in the cylinder? if it is just on the top of the plug, it is most likely your little ring gasket that goes in the valve cover, surrounding the spark plug hole. if it was on the inside, do a compression or better yet leak down test to determine where the oil is coming from. if both compression and leak down check out ok, then it is probably your valve stem seals.
