I had a valve adjustment about 5 months ago and they would have changed the seals right?
Problem there is that there is TWO sets of seals that can allow oil to get into the spark plug tube. there's the tube seals on the valve cover, and there are o-rings on the cam towers themselves. meaning you'd have to remove the rocker arm assembly to get at these seals. they also allow oil into the plug tube.
