Internet opinions from people who have never set eyes on the motor aren't worth much, but that sounds like a catastrophic failure to me. Overheat lead to something cracking (manifold?) or warping (head?) and coolant got where it shouldn't (cylinders?), and some metal broke or bent. Engine must come out, who knows if it can be rebuilt or you're looking at a new short block, long block, whole new engine. It's unfortunate but it is what it is.
