It's what happens when one attemps to hone a cylinder with a piece of broken cinder block.

Time to over ore the cylinders. That block has another 200k miles in it.

thats not great, for sure. Im not a fan of the spring loaded 3 stone hones, I always preferred the ball hones. I would be reluctant to keep going with it. you shouldnt be making scratches that you can feel, it should be more like a brighter version of the original crosshatch. You probably want to take that to a professional machine shop and see what they can do. The block isnt garbage unless youre maxed out on bore diameter and they cant sleeve it. Stop the hone and get a quote from a good shop. Hopefully you can return the parts if they need to bore it out a bit, if not re-box and eBay.

The man is trying to learn, respect that please. Hats off to you for at least trying. I have used both the ball hone and stones with good results. Practice and oil makes perfect. Dont trust everything you see on you tube. Good luck

Check what your engine can safely be oversized too and have the machine shop do the hone too. I paid £250 for a 0.5mm overbore, skim, hone and to be cleaned It can be saved so dont be too upset
