Thanks Dennis & John,
I'm pretty familiar with specified overhaul periods in the aviation world,
as that's where I earn my living. Fortunately those specifications are
based on something much better than the 50/50 survival rate for Dennis'
diesel!
I just now read the earlier posts in this thread (is it really a year old?)
and see Stuart referenced the GoWesty warranty period. Is it safe to assume
their 5% failure rate is while under warranty only? How about the quoted VW
of C rate of 50%? What's that based on? As Dennis suggested, some
documentation would be nice.
...and I still don't know how much warranty to give myself on one of my
rookie waterboxer overhauls. :)
