This past weekend I attended the All British Car Show in Bellevue, WA
and saw several great MGAs and Twin Cams, along with a vast assortment
of MGBs, Triumphs, Healeys and other British cars. It was a great show.
Mostly, I was interested in the MGAs, since I'm putting mine back
together now.
One item I noticed on several of the MGA and on the Twin Cam was a ball
valve shut-off in the heater hose. Now I know mine has never had one,
and I don't see them listed in the Moss catalog, so I'm wondering if
there is any historical precedent to their use? Having driven my MGA
mostly in the warm (dry) months in western Washington, I can see a good
reason for such a valve! I never have been able to stop the hot air from
getting into the interior of the car by using the heater controls.
Anyway, is there a precedent for this valve, and is it common practice
to fit them?
Thanks
