I put the heater back in the car. It fit pretty much perfectly. I won't be able to reinstall the ductwork under it that pipes air to the back of the car. Fooling with this unit I saw that it was here that my AC was leaking (green dye everywhere inside). If I want to repair my AC, I will need a new evaporator.
I noticed when I installed my sump that my cork gasket squirted out. I loosened the sump, shoved in back in and retightened, then thought about how annoying it would be to have it leak badly at start up. I ordered a one piece rubber ford racing gasket that has a metal core. Worth a few bucks to be sure I won't have an issue:
Here is the torn cork gasket coming out. Note that I used the smallest continuous bead of RTV possible and that pretty much coated both sides with no RTV squeeze out (but may be why the cork squirted).
New gasket looks great in there:
I wanted to prime the pump while everything was apart. There is a special tool for this. I used a 1/4 inch socket on an extension, but I risk getting it stuck in there. The electric drill will spin this well, but gets hot. The impact gun won't spin it without going into impact mode. Air drill is the hot setup. I spun it until I saw oil come out the lifters. Then put the rods back in and spun it until there was a pool of oil on top of all the rockers. #4 and #8 cylinders did not have oil come out. I think they are just too far from the pump which I am not turning anywhere near fast enough with the drill.
Here is the other school of thought on RTV. Everything I took apart was like this. It is not the way to go.
Here it is: like a monkey ready to be shot into space. Ready to sacrifice himself for the greater good.
