I would suspect the valve seals are worn. When you shut the engine off, the oil that is on the valve stems, slowly seeps past the seals into the combustion chamber. At start-up this oil is burned away creating the blue smoke. The oil will not seep past the seal while the engine is running. It can be fixed without removing the head but unless it get excessive, I would just leave it alone. Just make sure to check your oil level regularly, as it will eventually need topping off.
