As described, that doesn't sound like an issue (as in problem). If the oil fill hole is elevated 2-4 inches above the cam cover, the warm moist air rises and condenses there, where you can see it and wipe it off.
(If the oil cap isn't there, it'll vent to atmosphere, as suggested above.)
If the oil fill hole isn't elevated 2-4 inches above the cam cover the vapour will condense under the cam cover, where you won't see it, where it can drip on the cams, and where it is more likely to be re mixed with the oil when the engine next starts.
So this "issue" seems to be a benefit.
