Tony, remove the valve covers and do the add coolant bit again. It is
not uncommon for a failure at one of the head studs to allow coolant
into the cover and from there it drains through a pushrod tube into the
block. The lower 4 head studs on each side are inside the valve cover.
These studs first pass through the water jacket and then through the
head into the cover. A special sealer compound is put on each nut before
the nut is installed and this is supposed to seal the coolant from
getting into the valve cover.

I have seen several 1.9 engines where one of the stud corrodes where it
passes through the water jacket, breaks in halve, and then fails to seal
at the nut inside the cover. 2.1 engines are getting up there in age now
so this may be a growing problem with them as well.
