Depending on how far up the cylinder it is scored you  may be okay mark where the top of the piston is at bottom of the stroke before you pull it out you can then measure to the lower ring  and see if the scoring is affecting anything

It scored at base of cylinder, I think it should be ok. I honed it and it is not nearly as pronounced but still there. Now the problem is finding pistons for it. Anyone here have pistons for a p218g part # 112-0163? Where did you get yours best? Onanparts does not have them and I have seen used on ebay....

The Cummins dealer here also has Onan parts try Cummins -bridgeway. com . I'm surprised Boomer hasn't chimed in on this. Try Boomers influence. com

Tear down in progress, hoping new(used)Pistons, rings, hone will do the trick.

Wow, that piston is ugly.  I guess you found the source of the oil burning.  How does the cylinder look?

My thought exactly, how the cylinder didn't get trashed is a minor miracle

Right?! Cylinder wall had some grooves at base near crank and when I rotated crank and got piston to low spot of stroke it appears that the all the rings stay above the grooves. After honing the groves are much less pronounced but still there. I ended up pulling the other piston as well due to skirt being scratched up. I think I will probably have to replace that one as well, but the rings and top of the piston are not as damaged as the rear piston. What do you guys think?

Wow those pistons are ugly.  Have you measured your cylinders?  If the cylinder are in spec, I think I would replace the pistons and rings and give it a try.

Ran well before tear down, minus the prodigious oil burning! My hopes are it will run like a champ but you never know.....
