So I finally got around to replacing the distributor cap and spark plug wires. As discussed earlier, thinking it would be prudent to pull #6 spark plug while I was in there I went ahead and did it.

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?
