Did the previous owner say that the heater control valve itself was broken, or just that the heater core would continuously heat the air flowing through it and into the cabin of the car? When he 'bypassed' the core, what exactly did he do? Did he disconnect the two hoses from the ports on the back of the heater control valve (which poke through the firewall into the engine bay) and plug them or join them together? I just did a heater control valve replacement job on my 1985 900i and you're more than welcome to check out the web page covering it at "http://nospam/~c900/heatervalve.html" to see if that helps at all. With the one I replaced, the metal control shaft had broken off, so the valve itself is probably still ok (I haven't thrown it out - going to use it for a demo at a club meeting in the near future), but I don't think the shafts are available to buy on their own.
