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. :)
