I?ll run some more tests, but overall happy..

Coolant leak: I tried a new cap but still leaking.. I think it might just be corrosion at the inlet and I need a new tank.. anyone see this before?
Looks like the upper pipe nipple that is (I believe) soldered is leaking. See if it moves when you remove the hose and wiggle the pipe. If so, you might be able to remove the tank, clean and dry it and resolder the pipe nipple to the tank. Challenge will be to get the fluid out of the fractured joint so that you can effect a good repair. Absent that, it the same as the LT-1/LT-4, so you should be able to locate a good replacement.
