There is a seal for each of the plug tubes and by taking off the valve cover you can get to the seals. Replace the valve cover and the seals usually come with it. Put everything in. They eventually will leak so I suggest fixing it soon.

Suggested Repair

Replace the spark plug tube seals by removing the valve cover. A replacement valve cover usually includes the seals. Repair soon, as leaking seals will continue to let oil into the plug wells.
