I have exactly the same problem and currently also have the heater core bypassed.
The source of the leak was very, very difficult to locate. It happens that there is a natural path, due to accidental formation of the floor sections, in the firewall, cross brace and the rear floor well. After much frustrating investigation, I found that mine did not leak and then only as a trickle, unless the car was in use and the heater system under pressure. Pressurising the cooling system with the front floor and firewall area exposed, at long last exposed the problem.
Even after finding what was happening, it is difficult to accept how the flow path could exist. This could be one for the "how too" section.
As our winter is nearly here I have the job of getting to the leak, Has anyone some helpful advice, concerning the anticipated grief expected in removing all the decorative clobber.
