Well, I've been having to add a bit of water/coolant for several weeks;
haven't been driving it much for few months; hundred mile run 'bout every 3
or 4 weeks plus short trips/errands.

Interesting. So do head gaskets fail suddenly rather than gradually in the
rodbender scenarios? Could the fact that you caught it early have saved
the engine from bending a rod? If I recall correctly the problem happens
at no.1 cylinder. Will you do a compression test to confirm location at
the cylinder?

not driven long enough like this to foam it up. 'Drove it, maybe, 6 or 8

should check oil level again; next morning, checked oil and found MUCH
GREATER quantity in oil pan. Last time I drove it few days before, oil
level was normal.

Does your oil have a cafe au lait appearance? If coolant is getting in
there shouldn't it have that look?

Cold be either - one "kinda of inexpensive" while the other probably
very expensive as only a replacement head will do.
<<But does water in the oil mean head gasket or cracked head? >>
If the car has not been driven much in a while it could be
condensation as a outside chance. Unlikely but when a engine is not
allowed to warm enough to force evaporate condensation it will have a
grey gunk around the oil filler at times. But if a Oil Analysis was
done and water was found over more than one Analysis with lots of
driving between testing it is likely a head or gasket....
Since you are adding water but cannot find a leak it's possible the
water is leaking onto a hot part of the engine and steaming off before
you find it... Happened to me on a Chev years ago. Water was
leaking from a gasket onto the manifold and I had a very hard time
finding it. Of course of a Analysis test is done it will tell if
there is Glycol present...
