Re: 1950 packard 288 engine just rebuilt now has water in the oil

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.
