replacing rings

Hello,

I am replacing the rings on my bbc. I have a couple of rings that are broke. I bought a new set of moly file to fit rings. Can I save the old ones and reuse them again? The motor only has 8 passes on it. Rings are getting expensive now and if I can reuse them I will save them if not to the trash they go. Thanks for any info

I think something eles is wrong

If youre breaking rings with only 8 passes somthing else is wrong . TOO tight something by the way which rings are you breaking. I build over 50 engines a year for racing and many aplications ive never had a ring break unless the engine has been super hot or over 250 th miles and not many oil changes somthing wrong.

Back in the day. I used to replace only the top ring at re-fresh time on my drag car. Worked very well.

replacing rings

Ok I should have said this from the beginning. My bad. I had gotten water in the motor and I ruined the crank and most of the bearings. Come to find out the valve guides were bad. But that is another story. so I took the motor apart. When I was inspecting everything and I was having the new rods put onto the pistons I noticed some of the top rings and been broken. I would assume it was from the metal shavings that were in the motor from the crank and the rod bearings. I had metal shavings all through the motor. They were not to tight or nothing like that. I pulled each one off the piston and I put it back into the correct cylinder and I measured them to see if they were still with in specs and they were. So Thats why I am asking if I can reuse them or not?

Doc here,

Did you cut the ring ridge out with a ring ridge reamer?

IF not that is why you are breaking rings..

Every time you pass a ring over the ridge taking it out, it will crack the ring if the ridge is large enough..

ALSO be sure your not trying to put STD rings on a 10,20 or 30 over piston..look on the wrist pin deck, it will say STD..or 10,20,or 30 right on the deck.

Doc
