What does the oil on the dipstick look like? It's not uncommon for condensation to form inside the valve cover, and if you don't drive far enough to get the whole engine warmed up well, that slimy mess in the valve cover will stay there. A serious coolant leak will turn the crankcase oil milky, and make the level show above full on the dipstick. Give it at least a 20-mile drive as close to highway speed as is safe, and see if some of the slime goes away.
