Default 97 4.6L, oil soaked spark plug

My #6 spark plug is soaked with oil. There is no visible leakage from the valve cover. The truck burns minimal oil between oil changes, and generates no smoke. Any ideas where the oil could be coming from???

Oil may be leaking into cylinders past worn pistons or poorly adjusted or worn valves. Clean and regap the plug or replace it, but find out where the leak is coming from.
