there is an o-ring under there. It is not uncommon for there to be a small bit of oil behind the cap (reason for the o-ring in the first place). Check to see if the o-ring might have been pinched or damaged by whoever took the cap off last, or if it is even there still. If there is a large amount of oil behind that cap, you might have a different sort of problem.
