8N ring job questions

I am installing new rings into my 8N. All the cylinders looked great after honing with a 220 grit cylinder hone. On cylinder number 4, I noticed a very small area of shallow pits at the very top 1/2" of the piston travel zone. The pits are very small and shallow. Since I am doing the job with the engine in frame, I hate the idea of tearing down the block to have it bored. I know it's hard to diagnose from just a word description, but my question is, how critcal is this? The reason for the new rings was that cylinder 1 was blowing oil pretty badly. I never noticed a lot of oil contamination in #4. I know these engines are pretty simple and tough, so I am tempted to just re-ring and see what happens. Any thoughts or similar experiences?
Thanks folks!
Bud

Bud, Your engine should have sleeves in it so they can be renewed without boring the block. The pits you found are most likely from water or moisture in the cylinder at one time. I would check the cylinders for roundness. The manual allows for some slop, but too much and you should replace the sleeve. I would anyway, but that is my opinion. Good luck!!

Doesn't it have sleeves in it? I wouldn't worry about the pits that far up. Probably had water setting in it for some time in it's life.
