If working a diesel, bore/cylinder wear is just one thing to consider. Many diesels have wet sleeves that get pitted something awful on the OD where they contact coolant. Basically, the higher the horsepower, the more apt to be pitted. Also has something to do with wall thickness.
Also, when a diesel has bore wear, it just about always has top piston-ring groove wear and that tolerance is critical.
In answer to your specific question, if "no evident wear" actually means you inspect the OD and ID and all is pretty good - then yeah, you can reuse the sleeves. I've done a few that way, but it's pretty rare when that happens.
At the last Deere dealership I worked at, we had to pull apart many, almost new tractors - hone and re-ring without replacing any major parts. Why? Deere had a problem for awhile with rings being installed at the factory with all the gaps lined up instead of being staggered. It was causing excessive oil consumption. So, Deere advised that, if no abnormal wear or scoring was present, to just lightly put a new cross-hatch hone on the walls, install new rings with gaps 180 degrees apart and reassemble. Then load right away on a dyno to make the rings "set" and not walk around the pistons.
So, in those cases - we did it and it worked fine.
On a high-hour engine with a compression ratio 18 to 1 and maybe as high as 22 to 1 ? Things better be in awful good shape.

Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
