James:
How about the freeze plugs? I once sold a nice '63 falcon furtura
convertable after it did what you described. I assumed the head had cracked
and it was a goner. Turns out, the inline six had freeze plugs hidden by the
exhaust manifold. The guy I sold it to didn't offer to sell it back. >sigh<
Maybe you have a simmilar situation on your hands.
