<VV> Viton at GM

One flaw in that. The 5-year/50,000-mile warranty didn't exist before '67, so you had less than 49,000 cars with that longer warranty. The '66-earlier cars only had 3-year/36,000-mile warranties (or maybe less), if you go back to '60. I can't vouch for the warranties back that far, as I was just a kid and didn't get interested in cars until '63. My bet is that most standard seals probably lasted for the length of the 3-year warranty. Just enough time to clear it off GM's books, hence standard seal material was a respectable risk.

Our local Chevy dealer had at leas one Corvair a month in their shop, under the 50,000 mile powertrain warranty, in 1973. That far out, and still that many, is not fiscally responsible. OK, say, it costs GM an extra $5 a car, which at the time seems about right, given the time it took, it cost them at LEAST $120 just on the labor! So, they would have to have a failure rate of under 1 car per 50 to make it make money. We ALL know how failure prone these O rings can be, and at 50K miles, let's face it, most of us saw leaky O rings!

Not to sound like one of the extreme righties on VVtalk, but I'd have to
see your data on that one. I doubt that it was much, certainly not as much
as you seem to think, as to warrant GM changing specs for them. GM often
did things for shear economic reasons, taking the less-costly path that was
available. You also have to consider the multiplication factor. A few cents
per copy may not sound significant, but multiplied over the intended run,
and you're talking serious cost.
