Still love my car but......

Pull the timing cover so you can get to the rest of the bolt and then stuff the front of the oil pan with rags to cvatch debris. I personally like the heat and "back and forth" myself - usually with a good set of vide grips... You can also try the heat, the spray the bolt with the freezing stuff. If it still won' come out cut it and drilling it, then tap the hole for an easy out. If you're really at your wit's end - you're only about an hour from me. I can come help. It's really not this hard.
