Hi - I have a scratch that I can catch my fingernail on in one of the cylinders. Is it OK to remove a piston to inspect it, and then put back the same piston and rings if it is in good shape? Does it matter if the rings turn?

The scratch is toward the right of the cylinder. The dots toward the left hand side is just coolant. I know that the 'right' thing to do would be to bore the cylinders out and put in the next size pistons after a hone, but how bad does this scratch look?
Thanks.

you need to get it honed... get new rings too. the ring gap needs to be 90 degrees from each other.

Thanks.
I thought that honing the cylinders would only put back in those cross-hatch marks, not really remove enough material to take out a scratch.

Can you remove the piston/rings and then just put them back in without replacing the rings/honing or anything - just to inspect?
