People complain about the front heater valve not shutting off
completely and I see only a little of that on my van.  Sometimes if I
move the lever open then closed sharply a few times it seems to close
more fully.  I tried that on the rear heater valve this time too.  I
had marked a 1 and a 0 on the heater case to remind me which way was
off, and wanted to make sure I had it right.  After I opened and
closed the valve a few times it seemed to close better.

Anybody have a specific non-stock valve recommendation that they have
used on the heaters?
