Every one knows that an engine will eventually fail. The real knowledge is in the WHY? Is it a material/structural failure? If so, how many cycles till failure? Or was it an impurity in the material or even a treatment issue? Is it a design weakness? If so, what area? Not to insult anyone but I've seen way too many rod failures that were not started at the rod. I don't go to friend who's known a lot of sick people to see what’s wrong with me, I go to a trained professional. If you understand what one tiny spec of rust will do to one ball or roller on a bearing as it is subjected to the forces thrust upon it, the failure may not be what you initially see. I've seen guys say "oh the rod went". No, the rod was fine, it was the lack of good lubrication to the bearing that caused the bearing to stop and freeze in place, the rod had no where to go but bend on itself. Cranks will go. With the force it has to deal with and we are upping that all the time. If you want to cut down the potential loss of a failure then you need to service parts or even replace them before they are bad, but we (me included) wait for it to completely fail then we fix it. Pay now or pay more later.
BTW things like engine alignment will cause massive failures. Is it still aligned after that big nose in? You can buy the best crank but if you don't treat if right it will go to.
