2001 LS6 ring issue, they fixed it on the 02' LS6's. it just burnt some oil and had a little smoke after bouncing off the 7000 rpm rev limiter. since i am really pickey about my cars i wanted it fixed. plus as hard as i am on it with 80,000 miles 72,000 i have no history of i thought it was better safe then sorry or i would be buying a new engine like scott.
