thanks for the help though!
I'm a bit concerned, as the other 2 of the fronts were AC Delco Iridiums (just like the ones that I bought) but the one that was fouled was not - it was an AC Delco, but I don't know what kind. So I am thinking it is one of 2 things: either it was just a crappy plug and thats why it fouled and I shouldn't have anything to worry about now. OR (and I feel like its this, but I hope not) there is a some other problem that is letting oil into cylinder 1, and the previous owner knew about it and just replaced that one plug as necessary. This would probably explain why I am burning oil... and it would probably be a very costly repair I guess, right? like a piston ring or something maybe?

How much oil is being consumed? Could just be bad intake or exhaust valve guide seals on that respective cylinder.
On the suspected bad spark plug, which specific AC Delco was it. I've been having bad luck with AC Delco Platinum Rapidfires in one of my other "W" bodies. Some form of manufacturing defect.
