I am in the process of getting an estimate to do a preemptive rebuild. So far they have only said the labor was about $14,000 and they would need my ESN to determine the parts price which I sent them yesterday. The latest rebuild kit includes new carbon scraper liners and matching pistons

I have an actual bill from another owner that already had it done at the same shop I'm going to use. It was around $26,000 but included extra work and parts for the chassis.
There was a thread started by someone with a newer ISX12 and had been almost a year now and not out of the shop.

Is that head only or will they be replacing all pistons and rings?

The latest info from Cummins is that the carbon scraper liners and new pistons are part of the updated kit for ISX's. I asked how important it was in low mileage, light usage like RV's. They never really answered other than as below.

To answer your question regarding the carbon scraper liners and pistons, they are part of the updated kit so they will be included.
So, evidentially Cummins has a specific "kit" out to install when your valves break.

After two weeks of inspections,fluid analysis, report interpretations and irv2 information , I have decided that the answer to my post of ISX yes or no is NO. I will continue to use my Allegro Bus until the timing is right for me to start looking again .
Thanks for all of the good information from the forum.
