Stolen from a Mopar Facebook friend

I've used a hand-drill stone hone. Neither those nor the ball-hones will fix an out-of-round cylinder, but the machine hones at shops will. Per TV shows, you actually hear them change from a whack-whack sound to a smooth sound as the cylinder becomes round. Shops usually hone after an over-bore. I've read that one can buy 5 mil over pistons for a few engines, but don't know about Mopars. You would likely need those if not overboring and rounding out a cylinder, if enough metal left.

The latest I've read, is if you see the OE honing marks everywhere in the cylinder, that insures no significant wear and still round since those scratches are only ~1 mil deep. That is not unusual in engines since MPFI became common (1990's), even at >200K miles. I think it was running rich, especially when cold, which put raw gasoline on the cylinder walls to cause rapid wear. Diesel engines never had as much wear since the fuel is a decent lubricant. Today, the consensus is to not even scratch-hone if you find the OE honing marks, just install new rings and can re-use the OE pistons if no cracks. But, if using cast-iron rings, new scratches might be good to help them wear to seat well against the walls. If you do, clean the cylinder walls very well with soapy water to get all the grit off, and keep going until it passes the white-glove test.
