This problem may also occur when oil is poired into the engine. If there is an overflow the oil tends to flow down the side of the manifold towards the plugs, which as you noted, are great recepticles for oil.A quick test is to clean out all the oil, I used paper towels, then run the car around for a day or two and check again. If the oil is back ( and you haven't topped up the oil in that time) then you have a leak. If not then the problem is solved.
Good luck and tell us how you go.
