MGB Heater Valve

["Tyson Sherman" <tsherman@tecinfo.com>]

The heater valve in my 76 B was replaced in the engine
rebuild, as the old one was frozen.  However, the
first time I tried to adjust it it broke.  I keep it closed,
and today noticed that it was open.  When I opened
it, water began to drip out (onto the distributor, strategic
location!).  Is this a common problem for six
month old valves, or is mine defective?
