Hatched piston, opinions wanted on build

So, toasted #2 piston now pulling the cab so I can take it all apart and see how bad the cylinder is. Running my options right now and looking for advice.
1. replace bad piston, ARP studs and slap it back together if cylinder looks good
2. replace all pistons with HD ceramic slugs if cylinders are good
3. full rebuild, pistons, bearings ect if machine work is required

Question to you guys is how many have had a piston go south and have had only the bad one replaced?
My thoughts are to do them all, but my wallet is asking for second opinion

Cheers all

Talking

Right now, mine is sitting @ Rudy's diesel performance with a cracked piston with 105xxx on the odo. I feel that if one cracked and I just replace that one, I have seven other pistons with same wear and tear, so I would at least do all eight of them. On the other hand, he already has short blocks ready to go with a 3-year, unlimited mile warranty, so I'm thinking that is MY best option as I haul cars across the southeast US. Good luck with your decision whatever it may be.

Mines a 01/07 build as well. How many miles on yours. Do you get on it often.

Only had the truck a week, knew it had issues when I bought it (Calgary).
I'm not hard on cars per say, but I want to know she can take the mini maxx hot tune all day long
Has 258,000km, and I drover it 800km home with the toasted piston getting 18mpg (hand calc), but I did use 7 litres of oil..
Thinking a bad injector took out the piston, as #2 stuck open a time or two on start ups.

yup, contribution and misfire on #2 (not when I was looking at it but the next morning lol). pouring white smoke. restart and fine.
Funny thing was driving it was relatively fine, not miss, no knock, lots of power.
I knew the truck was going to need work, just not an engine! oh well, still better than forking out 70k for a new one.

Man groove you have had some bad luck. IMO I would replace all of them with HD or international pistons if money permits. Once the pistons are upgraded I haven't heard of anymore problems cracking them.

If he drove it home with that piston like that I am sure international pistons are out the window since they only come in stock bore size correct? I would contact Aaron and the guys at Rudy's and see what they have to say. They also have great prices on parts and great customer service

I thought I read that international pistons could be had in .20 over bore but I am not sure on that. I would also look into the HD pistons from Rudy's.

I may have a good line on International parts, so that's an option. Other than that looks like Rudys will be getting some business from me. Should have engine out next week, that will determine how far I need to go. Hopeful that the block and heads are good. Will keep you all posted and take some photos along the way.
