Intermittent crankcase pressure issues

Are you seeing any signs of oil on your spark plugs, either on the electrodes, insulator, or around the threads?

Looks to be some around the threads but the area was kinda soaked on this one because it was sitting under the breather. The rest were pretty clean.

Should be pulling a head tomorrow and taking it apart tomorrow. I don't mean to offend anyone trying to help. I suppose NOTHING is really conclusive at the moment and we all just have educated guesses at this point. I'm not completely ruling out the rings which is why I pulled the whole motor and not just the heads.
