I'll get out there and start looking. I'm not exactly sure *what* I'm looking for yet. I've never seen a "good" one, but based on some pretty good pics I saw earlier : I've got to think I could probably at least rule it out. It doesn't appear to be dexcool related.

Based on advice so far and my experience with old cars (60's muscle)... steam in the exhaust & burning glycol usually says "blown gasket". Of course, I'm just not used to thinking about an IH gasket so my head doesn't automatically go there. Yet.

That's a very diplomatic way of saying "calm down, dude." OK. I will. All my tools are at my office so I'll either find some usable implements I've forgotten about in the garage, or I'll pick up my tools tomorrow and dig in. Thanks for the motivational words.
