Nice story !
The 'impeller face' on the engine block- eyeball that, make sure it's not
too trashed up.
Personally, I don't think it has to be 'just perfect' ..
it has to be mostly all right.
There is some leeway there.
I think that there was likely not that much loss of coolant flow with that
piece of impeller gone. Like could still pump maybe  75 to 80 % as well as
if intact.

and hey ....at least you found a big fat 'this is not right!'.....
far better than having a problem but you can't find anything obviously
wrong.

that piece laying in the engine ....I don't think that would have hurt if
left there.

yup....two old Gatha's ...
one - 'FOD' - foreign object damage, an aircraft term.
the other ...
Workmanship.   Somebody hadda drop that nut in there.

makes for a good vanagon story too,
thanks for sharing it !
