Glad I did......(see attached)
I really can't tell if this thing has ever fired! And I don't get the sense it's oil vs unburnt gas. Could it be that the #6 was never getting spark or atleast not reliably via the spark plug wire?
I'm kinda at a loss why the CEL is not informing that I'm missing or something. And furthermore, why isn't the 80 running rougher?
Is there a good test to confirm that spark is actually coming down the wire and firing off the plug?

Believe it or not - but that plug is probably still firing OK. Oil is not inherently a conductor so it will not immediately affect the spark. After a while the heat and electricity will more or less create a conductive path to ground that will sap the spark and make the engine run like it did. It will happen again and, unfortunately, as you know #6 is not easy to get to for a quick replacement. My bet is still on the head gasket being the culprit at this point. Are you sure that there are no signs of trouble in your overflow? Does it pass the bubble test?
Amherst is real nice - we used to have a house in Nashua about ten years ago and I always had wished we bought in Amherst back then. This time we headed East to Chester - lots of property and motorcycle trails to play with my kids on.
