Are you talking about the drain hole. It drains any water that might get down in the spark plug well. If that is the case I'm not sure about oil coming out of there.

yes,the drain hole for the spark plug well. i have oil seeping out that hole when the bike is running.
im hoping it is a bad top cover gasket not sealing around the spark plug hole.

That's what it sounds like to me. I would pull it off and look for any pinch marks from where it was not seated properly.
