So I may as well continue the controversy. I just got home from the shop. I was able to pressure test the coolant passages of the block. I blocked off the raw water pump, and the hoses going to the manifolds now removed. Using an automotive coolant pressure tester, I cut an adapter used to test radiator caps so I could hook that to one of the hoses. Then I attached the pump and guage to the hose.
I pumped it up to 18 psi, and it held steady for about 10-15 minutes.
So now I presume the port manifold was cracked externally. But it was the starboard side that was cracked internally as it was that side #4 (if I remember right) that had low compression (100 psi compared to 130)
But now I know the block is serviceable for rebuild this winter.
