Hi Don et al
I have an early model 1965 A4 and have a persistant weeping of cooling water from under the alternator bracket on the cylinder head. I first thought that it was weeping up the head studs at cruising revs under load, at idle it does not leak. On further inspection there is a 1 inch hairline crack in the cylinder head adjacent to the center row of studs, oozing cooling water at cruising revs. Obviously it needs considerable pressure to make the leak. The engine runs well but I have noticed an increase in steam/white smoke in the exhaust.
Bottom Line - is there a hopeful fix without having to buy a new Head. Anyone had any experience with either welding , or automotive type sealer compounds
