As far as I know you can't tell by looking at it. Eventually the rods,
crank, or other components will fail due to fatigue, but it tends to be
a rapid process - if you happened to Magnaflux it just as a crack formed
you'd be okay, but propagation is rapid in fatigued parts.
Bucks-up and factory backed racers do it by the numbers - so many laps,
passes, or miles, and all the shiny expensive parts go in the dumpster
or used-race-car-parts-for-sale bin and new shiny expensive parts go in.
