Well, to be completely honest? I dunno what was wrong, but after tearing it apart and putting it back together again, all seems to be well and good! The water pump gasket I suspected? Was fine. The head gasket? Still new and perfect.

I give up, but I'd rather be lucky than good ANY day!

Be driving by between 0030 and 0100 Thursday morning (Wednesday night, if you prefer). Hope yer awake! LOL
