I started it at idle (removed throttle rod and put the spring on in
its place) and noticed quite a bit of water blowing out of the exhaust
manifold, complete with hissing and other scary behavior.  Also drips
from the manifold nuts.  I was a bit concerned, as I've no idea how
much initial condensation water is supposed to blow out of an engine
like this.  I don't really have that much experience with big iron.
So I pulled off the exhaust manifold and fired it up again.

Hmm, #6 is blowing cold air, not warm.  I'd wondered about that based
on the condition of the cylinder head when I pulled it.  Also, the
engine didn't run as smoothly as it seems to me an I6 should have.  I
pulled the #6 wire and there was no spark.  I stopped the engine and
removed the wire (which is a replacement and unlike the others) and
found it to be open.  I removed the distributor-end vampire clip and
that end seemed to be OK.  I noticed that the other end was torn some
at the metal clip, it's possible that it was yanked on or something.
I pulled the clip off and jammed the ohmmeter probe into the neck: no
continuity.  So I cut off about 1/2" and tried again.  I had to cut
off a little over an inch in 1/4" bites before I got continuity.
Fortunately there was enough slack in the wire to still reach.  With
the wire somewhat reassembled the engine ran much smoother.

After #6 was firing, it also blew warm air and water out of it like
the others.  I let the engine idle long enough to warm up quite a bit,
and all the water stopped coming out.  Just condensation?  Seems like
it might be, and I _really_ hope so!

Thoughts from the experienced among us?
