Of course the problem was the EGR port seal which was cracked & degraded, but even worse was the small one beside it. Everything is finally back together and flushed with new oil and coolant. (Things don't go as fast as I'd want them as we had two deaths in the family.)
However, it will not start. I stroked all of the cylinders to TDC and blew them out with 110 psi air to dry them prior to installing the plugs, so it turns over but doesn't even want to try to start. I checked all of the cables, even rechecked my sparkplug wires, made sure the fuel rail was full, and even tried a shot of ether. Nothing.
