Default RE: Replace liner?

Honing and breaking the glaze on the cylinder wall are not the same thing.

Honing is the final step in sizing a cylinder for piston fit, it actually removes a measurable amount of metal.

Breaking the glaze to assist the ring seating ideally removes no metal, calling this operation "Honing" is a misuse of the term, even though it's common.

No, don't replace the liner, or the piston either if the fit is still good.

Do not try to eliminate all the "Shiny" from the sleeve, just scuff it with some light oil on 600 paper wrapped around your finger. Having worked with auto engines you already know the crosshatched pattern you want.

I've re-ringed model engines both with and without breaking the glaze, I really have not seen any difference in the speed of the new ring seating. You do as you please, I've gotten away from it as even the lightest scuffing does remove metal,
