I mistrust the installer. If after 10 hours of diagnosis he can't *confirm* the cause (I think a simple chemical analysis of the coolant would determine whether or not the exhaust is leaking into it), I'd not use him for diagnostics. I suggest getting a qualified technician into the loop: 1. Have him do a diagnosis up front (talk it over with several and choose one based on their experience and knowledge of the problem). This shouldn't cost too much. 2. Take the results to your installer and/or rebuilder and insist that he carry out the indicated repair. If he's not using quality parts (VW or OEM), maybe that's the problem. Weren't the heads checked for cracks when they were removed?
