Re: 65 Heater Box Help

[John Hammond <426_maxwedge@xxxxxxxxxxx>]

This is by no means a concourse method and I've yet to test it under 
pressure
but I can't help but think this is gonna work great on my '64 330.  I 
removed the
valve from the box, (Brass - 90 degree looking affair), and noticed that in 
the
90 turn was a valve, hole, sensor, something at one time or another, and
obviously a source of a leak. I removed the remaining guts of whatever this
had been and plugged it from both inside and outside of the tube with a 
2-part
epoxy putty taking care not to cause an internal obstruction with the 
compound.
Pack the putty into the inside corner with a pencil or some thin probe. 
Clean up
the outer tube with some Brasso and go find a replacement O-Ring at Napa. 
This
part is now ready to re-install using the screw through the plate back into 
the heat-
er box. Mine was stripped out so I went to a larger size to get a good bite 
and a
firm connection to maintain a good o-ring seal.  My boudin cable wasn't the 
best
and seeing as how now we have no valve control anyway,  I purchased an 
inline
valve that goes in a heater hose and is cable operated; and mounted this 
almost
nipple to nipple with 3" section of heater hose on the inlet tube. From this 
valve
I used a garden variety universal choke cable and ran it as straight and as 
short
as possible to the dash area for good activations.  As luck would have it, 
this
arrived just to the left of the ignition key in an unoccupied spot. Using a 
spare
knob/switch bezel behind it, most folks won't even notice it and those that 
do
will assume it's a factory accessory.  NAPA sells a valve of this type, 
(straight
through, about 4" long, with the cable slide pins on the side), but it's 
about $40.
with plastic guts. I found a smaller unit in all metal construction from a 
street
rod parts supplier for $17. so some shopping around for this type of setup 
can
be beneficial.  I have yet to check for valve cover fitment issues though I 
doubt
it will be a problem. If a problem does arise a simple, formed 90 degree 
elbow
hose will point the valve toward the hood hinge area and the cable is 
attached
to the valve via a screw held clip so a redirect will be easy and may even 
aid in
heater hose routing at the cost of a slightly less efficient cable 
activation ability.
This solved two problems at once for me and hopefully it can be of some help
to others here as well.  Seems as if I remember a similar setup being used 
from
the factory on some models between like '71 to '76 but I'm not sure of this.
