<VV> Air heater

[Mike Jacobi]

I think there's a huge difference in a design meant for a car that was
thought to have a life span of 5 to 7 years tops, and one that is used by
the same car, used by hobbiests, 40+ years beyond its original concept life
span.

When these cars were new, a hot air heater designed as ours were, vulnerable
to age induced exhaust gas leakage was acceptable.  After all, long  before
there were serious gas leakage problems, the car would have been melted down
and been recycled.    And if leaks did happen, well there was the dealer
network and warranties and all that support stuff available to the owner.

Our cars of course are way beyond dealer support.  When we look at this 60s
era heat  design, we see that it is clearly trouble prone and even dangerous
if not closely watched and maintained.

Therefore, I think it's safe to say that in the context of it's design, the
heat system was acceptable.  Far far better than that on the Volkswagen of
the day.  Nearly 50 years later tho, in the context of our hobby, we wish
for the safety and reliability of those in the water-pumpers.

GM did a pretty decent job with this car.
