wow, that is a lot of wear all the way around on that thing. Almost looks washed out a bit like maybe coolant was getting into it?

There is also a lot of lateral thrust wear from what i can tell ... a bit more than usually seen...


Did that thing have any custom programming in it?

If so, then send over a copy of what is in the ecm and I will review it for ya.

Here is something for comparison .. this is a liner photo of a well cared for engine with a million miles on it. The thrust wear can be seen but it is not a whole lot much more than the rest.
   

and here is a liner that was severely abused by a bad (PeeDeeEyeI) delete. the injection timing was upwards of 15+ degrees at 750HP and high torque. Lateral thrust wear from excess boost and timing was so high that is split the liner.
