Well, the engine was fairly clean, and a good assumption, however if it was
a leaking cap on the bottom, or a leaking shaft seal, given the limited
visibility, I believe even a previously "Gunked" engine/pump would obfuscate
the source.  And when I said "source obscured," I'd meant (and specified)
that it happened when the pentosin lines where removed and overflow from the
lines spilled on the pump, not from huge amounts of time in negligent/dirty
use.

Yep, and between monitoring the reservoir, and looking for leaks at oil
changes, that's how I was able to confirm to Houston that we had a problem.
But bi-annual, that almost sounds to me as "fat-time syndrome" (see below).

As it where, I'm pretty sure it was the shaft seal leaking based upon what I
could tell from previous inspection.  Contrary to advice, I went to a shop
and had them press on and off the flange; some of the external sides of the
seal (ie o.d. of seal) did look to be oiled.  I also figured, since I had
all the parts for the same price as some of the parts, might as well replace
the lot.  We'll call this "fat-time syndrome," a correlary to "fat wallet
syndrome."  As I had the time now, and the materials to replace everything,
why wait till tomorrow when I might have neither.  I'm with you to a
point...

Too little too late, reassemebled at this point with pentosin lube.  We'll
see what happens in the next day or two when the car is reassembled.  I'll
be wearing safety glasses!
