oil pressure disappeared.

If what you are showing is the problem, you had better inspect "the heck" out of the intermediate shaft, and BOTH distributor gears, AKA the cam
I would hope that the oil filter would catch any other wires that were picked up. If they are in the motor, I am screwed. I have not cut open the filter yet. I may do that later this week. When visually inspecting the cylinder bores from below all looks good.
