<VV> Viton at GM

[jvhroberts at aol.com]

 Heck, at -30F, Viton MAY leak, until the engine warms up, and as soon as it gets anywhere near 0F, the leak will stop! Which would take, what, 45 seconds? LOL

If I drive any of my Corvairs where it is -30, I'll take heed and put Buna-N
back in.  The Viton will most likely be there for the rest of the cars life!

I have a buddy who worked at GM as an engineer right out of Purdue. He
remembers (less than fondly) the low temp tests in the Great White North.
-30 F type stuff.
