Thanks Zakhar... That does help..
Looks like I overfilled it a bit when I topped it off, so that was the overflow coming from exactly where you describe the overflow would come from.
But my leak is coming from the hoses that run under the intake manifold.. I'm going to top it off and drive it to my mechanic (about 20 miles) tomorrow morning...
I may have to pull over and top it off a few times, so I'll have a few gallons of distilled water with me. Good times.
