Did you rotate the crank to different position. Retest every 90 degrees so make sure a single piston rings are not sealing a pin hole bore defect in one positon.

I will first say i have very little experience with Packard I-8.
I have worked on a lot of inline flathead everything else. The "wet" condition in the intake runners, and "to clean" spark plugs makes me wonder if there is a source point that is drawing water from your cooling system, (via vacuum in the intake), and then feeding it into your engine. The only thing i can come up with would be the double acting fuel pump. I can't find a good schematic of everywhere the water jackets are in the block. Wondering, its a shot in the dark, if there is a jacket near the fuel pump mounting position on the block. Maybe. If it is possible, to get a coolant leak in that area, would it explain water in the oil, and the "wet" intake runners ? (I am not familiar with double acting pump so not sure if this is possible) I have seen the leaky cylinder walls on freshly bored blocks before. The L-134 Willys blocks, L-218 Dodge engines, and more than hand full of Henrys V-8's. Pressure testing always seemed to do the trick. Could always find droplets leaking out of the walls.(No pistons installed) I maybe, and probably am, completely wrong about the fuel pump thing. Just shooting the dark for another idea.

Yes I had each cylinder at BDC and TDC and one point in between. I hate to say it but I was hoping to find a pin hole in cylinder bore at least that could be repaired by boring it out and having a sleeve made. At least I think it could repaired if that was the issue. Now we are starting to wonder if the sealer worked after running it for 1 hr draining it and letting it set overnight to cure. Unfortunately the sealer damaged the crankshaft since some of it had to get in the oil before sealing the block up ??
