" If the “cross hatch” is still visible in the cylinder and there is no scuffing you can try just new rings. " ---Anthony Cerami

Have you ever seen this concept written in a manual or rebuilding instructions for a diesel ?

My rule is " New rings , New crosshatching ". The function of crosshatching is to aid in the seating (wearing in ) of the new rings.

The exception is some air cooled small engines where chrome rings are available for rebuilding which are hard enough ( and typically work in aluminum bores ) to cut their own space.

" If you reuse the pistons do not clean them ! Simply wipe them off with transmission fluid."

Cleaning pistons during a rebuild involves getting any carbon off the top and cleaning the ring lands so that new rings can function properly. The instructions in the shop manual are very specific.
