The plug is an "outie" just like the picture linked in the first message of this topic. It sounds like the MAP gas and a big pipe wrench should do the trick. I just wanted to make sure there wasn't something obvious I was overlooking. I also have some PB Blaster and I'll be sure to pre-soak it before I work on it again. I'll also try to remember my camera and post up some pictures--we all like pictures! Thanks for the help.
