<VV> Viton O ring life

[John O'Shea]

I used Viton O-rings when I rebuilt my engine in 1977.  I just overhauled 
the engine earlier this year and put in new Viton O-rings, but I'm not 
convinced I needed to replace the O-rings from 1977.  They were just as 
pliable as new when I removed them.  Could they have gone another 34 years? 
Maybe.

Jack in Las Vegas where it's 105F this afternoon.
