Like Dirk said, it happens.

When the nozzle splits or breaks it starts dumping more raw fuel in there, which takes out the piston.

Did you crank the truck over with all the injectors unhooked before you cranked to start?

You can split a nozzle if you don't have fuel flowing through the nozzle to lubricate it while cranking.

Is there any way to know this happened before the piston fails?

How do you know? does it run rough? stall? or is it that once it happens, you are dead before you know there is a problem?

When a nozzle splits there's lots of white smoke out the pipe and the motor usually knocks. Shut it off immediately and get it fixed.

I have seen a few oem stock nozzles split, and some EDM'd used nozzles, but never a new one like the ones Casserly uses. The oem stock ones we assume there was water in the fuel, or possibly just fatigued.

I had one customer that split a nozzle, stock oem, and the guy didn't want to pay the $$$ to have them all replaced. 3 days later he was 100 miles from home and split another one.
He then decided it was a good idea to replace them all...
