This
is just theory, brain storm or brain fart - you're the
judge.
One
thought: Flush with a solvent that binds with water, and evaporates easily, and
that doesn't eat up the internal seals.
So
perhaps a flushing with denat. alcohol or avgas prior to blowing the case dry
with compressed air will remove a lot of water.
Alternative two. Take the engine case into a sauna and let it heat
up for long enough so that steam escapes.
All
right alternative 2 wasn't that serious.
Memory
is fuzzy on this one but I recall, running pure antifreeze is a corrosion
problem.

And I suggest that
even using that drain plug is not enough. For this tear-down I used that
drain until it wouldn’t drain anymore. Then I still got out copious
amounts of coolant at various stages of disassembly. I am not sure what
the best procedure is.

I'm thinking that using
the drain, along with rocking the engine forward and back, would get most of
the coolant out. In your case, the rust is plugging up the holes, and
making it hard to drain coolant that's above the rust
level.
Does anyone know of a
good preservative that could be used to fill the coolant passages?
How about just straight anti-freeze? You wouldn't want to use
something like oil, since it would be hard to clean
out.
Cheers,
Rusty
