Theres an oil journal less than .5" away from the #2 spark plug tube. It is usually the culprit for oil in at least the #2 tube.
I replaced all my tube seals and adjusted my valves early May, along with 4 Autolite spark plugs (not NGK, btw), and have had no problems. No leaks, no performance issues, its all blue skies as far as leaky tube seals or oil on plugs goes.
