<VV> viton crank seals

[John Sweet]

Bob,
 I had atleast 3 failures on the crank seals.  One customer wanted me to 
install the viton crank and balancer seal and the bellhousing seal failed 
in 500 miles.  I had to replace it at his expense since he requested it. I 
put an aftermarket seal in which has a double lip and the seal has not leak 
since then. We had discussins at the performance workshop and at the Ft 
Wayne Meet last year and other people had the dame failures.
