Non-FE Discussion Forum / Re: Why new Rings, Why rough up a smooth bore?

I get needing to hone them for NEW rings, if I was planning on another 100k+ miles that makes perfect sense. What I don't get is that the same polished rings back into the same polished bores supposedly is crazy and will use lots of oil. If it wasn't using oil before why would it start from simply removing and reinstalling the piston?
And how the heck does a rod bore spread towards the parting line and tighten lengthwise? One rod has done that by about .0015"
