I just found out something over the short vacation I had and a visit to the
local German Auto repair in my area.  I thought that the coolent was leaking
from cracks under the sparkplug holes on the heads.  According to this
mechanic, those cracks cannot leak.  Is this correct?

If that is the case, then I would suspect the head bolt.  Both are right at
that spot.  Maybe this has been my leaking problem all the time.  Any inputs
appreciated.
