file to fit rings for a bbc

I have a question about file to fit rings. I had a ring break its the 2nd ring on number 7 cylinder. I have another set of rings but they were used for 10 passes before I had to rebuild the motor do to a spun bearing. I think I have them marked for what cylinders I took them out of. COuld I use them for a relacement or shud I buy a new set of rings??? ANd if they aren't marked would it be wise to use them??? I was thinking I could put each one in the cylinder and measure them to see if I could find then one that was on that cylinder but I didn't know if I was off any on the measurement of the ring if that would be a problem?? any help would br greatly appreciated.

I guess you are installing new rings in every cylinder and broke ONE ring.

I have seen people install a little used ring with no problems on a fresh cylinder deglaze/hone job,

but I sense that if you purchased a new ring set for one piston and installed that new ring, then you would at least know that you did your best.

As long as your end gap is right I wouldn't worry about it

I might suggest to you that you have a bigger problem than just one broken ring blowing compression out the valve cover.

Second rings scrape oil down as much as they hold compression up, so I think that you should look for other problems too.

and blowing oil
