Pull out a couple of plugs and look at them. If they are oilly on the tips, not the sides but in the area of the electrode you may have a broken oil ring or something that is causing the oil to get into the cylinders. The overheating is most likely related. Is the level of the coolant dropping as well. My observation would be that if there is oilly deposits on the plugs and you could perform a compression check, but I would opt for a new engine.
