No sleeves so you can’t fully rebuild one in the bus however they can be machined.. Ie normal wear-out you can bore it .020 over and use oversized pistons. Cylinder damaged then it can be bored and service sleeves out in. At that point though you are usually better off money wise to purchase a reman short or long block depending on what your parts need is. Machine shopping a block makes sense for someone who is doing the rest of the rebuild themselves .. ie re assembly ..

For me even though I can rebuild an engine if I wear or break mine I will just go buy a “ready to fly “ reman unit . Financially it makes sense to do so unless you already recently say replaced your iniectors and turbo or your engine is built high performance (big turbo big iniectors big HPOP) then it makes sense to get a short block

I remember reading I believe this is a non sleeved motor? I am unsure how this plays into rebuilding. Some "expert" on a FB group says 7.3 can't be rebuilt for this reason... likely bollocks, but thought I would ask anyway

Confess I know little about rebuilding engines... most of my experience has to do with repairing and whatnot things attached to said engine.. I have little experience with pistons and rings and all the things INSIDE an engine

Mine is fine now, and I care for her well

but curious
It can be rebuilt. However not in frame. It has to go to a machine shop and be rebored, like most automotive engines. The heavier truck engines have removable sleeves that can be changed in frame. Meaning while the engine is still on the vehicle. Pistons and rings are part of the sleeve package

Here is a liner and piston set from a detroit.

cute piston

and good to know

pulling a motor does not scare me

taking apart the internals does

the dyscalculia I think and specs and etc would be an issue so I stick to what I know

cheers
