check all coolant lines in the area first.
pressure test the cooling system to find the leak.
chemical sealers work for a short term solution.
it is best to replace both heads at the same time.
they have seen equal conditions and the other will let loose soon after.

coolant here and there and when I try to find the source it seems as
though it's the driver's side head.  This is the side that can be done
easily (!) with the enigne in, right?  Anything I should be ready to
change at the same time?  How long do I have until it absolutley must be
done?  I have no coolant in the oil and no hydrocarbons in the coolant and
no apparent loss of performance.  Hmm. . .
