I have the 53 block it has 75,000 miles on it as you can see in my signature it is lightly tuned nothing wild, just wondering if i should be worried about the block cracking or not??? if so where and when do they usually crack, what are my options, does tuning them increase the chance of cracking it??? Thanks for any input!!

 

I have 139k on mine, mods are in Sig, no problems. It's not a 100% chance it will crack, but higher than the other blocks. To me, don't stress over thing you can not handle. But someone might chime in on more help than me.

 

nothing dont worry

 

k, i didn't know for sure what the deal is with them?? i heard cummins actually stands behind them really well if them do crack anyone know anything about that?? THANKS Guys that helps me sleep better at night!!

 

It seems like the chances that it will actually crack are somewhat slim, but definitely more likely than the other blocks.

I think it cracks on the passenger side, starting near the back corner, about halfway up. I can see where mine would crack because of the pisspoor casting job, but no signs of cracking yet. I don't worry about it much at all at this point, just check the coolant level every once in a while.
