I have seen several cracked pistons on here with a bad spray pattern which suggests probably a leaky injector (especially if the other pistons don't have the odd spray patterns). I figure that design of the stock pistons also doesn't help. Maybe since IH pistons seem to be better, they would be able to take more abuse from a leaky injector longer so hopefully you would be having symptoms of the injector issue before the piston cracked. Short of reading the temps in each cylinder, is there any way to prevent the next failure?
I would think cylinder pressures rather than temps would be a better tell tale sign of a problem, or a better factor to control to keep pistons together. Either way, without identifying what the problem is, there's really no way to know what we need to do to prevent it.
Seems as though for right now, with no rhyme or reason to pistons breaking, maybe it's just a crappy cast in come situations?
If that's the case, I would imagine that IH pistons would be a solution.
