Cam seal is worn out. Inevitable on this engine, but not too bad to fix.

I have a 1982 Merc 470. After running it for an hour or so the coolant
level
is normal. It can even set for an hour and still is fine. But when it sets
overnight thecoolant level is down. Sometimes a pint or 2. No leaks seen.
Where could it be going and how would confirm it. Thanks...
