you need to find a friendly dealer if you are going to try for the rering procedure. The last I heard GM had changed the TSB in this and if the car doesn't use more than a quart in 600 miles they won't touch it. So do some checking and do it soon before you embark on this adventure.
Good luck.

If my 01 Z06 would have used just half a quart in 700 miles, I would have been very happy. Mine was using a full quart in 600 miles. I doubt that I'd bother with the re-ring in your position.

Have an 01, 17,000 miles and 6 months left on warranty. Is half a quart in 700 miles a problem? Tell me what you experience please. :flag
In my book less that 1 quart in 3000 miles is normal. Any more than that and I would start checking for carbon build up on the pistons and combustion chambers (resulting in reduced fuel economy, reduced power, detonation/pre-ignition, etc.). If there's no carbon build up, then it should not be a problem (other than cost/nuisance).
There are many ways to use oil: rings, PCV, intake, etc. If there is an issue, check the simple things first.
It's possible to use 1/2 quart (or more) during certain high-temp / high performance conditions. So, a one time, short interval, 1/2 quart burn may not be a problem. Keep checking it to know for sure. :cheers:

It depends on how wound up you get about adding oil. Our 01 gets anywhere between 1500 and 2000 miles a quart and I'm perfectly happy drving and owning the car the way it is.
I just can't see getting all excited about adding less then one quart of oil between oil changes, so I'm not going to hassle with trying to find a dealer to do work that I really don't think will make any difference in my use or enjoyment of the car.
If you have some sort of religious belief about a car not using less then a quart of oil every 3000 miles, I suppose you'll worry about it.

Here's ~1.5 quarts in ~1800 miles (symptoms: pinging, 11mpg (soft driving)):
Pistons were also heavily carbonized along with scored cylinder walls.
A borescope through the spark plug holes can be used to quickly check for carbon.
Again, if no carbon buildup, no worries. :cheers:

The GM TSB states that 1 QT in 2000 miles is excessive. I don't know where people have gotten this info that it is now 1QT for every 600, but I just started the oil consumption test and the TSB is still 1QT per 2000 miles for the repair.

While searching for the TSB, I found these sites: http://www.pistonslap.com/ http://www.lemonaidcars.com/up_june_december2002.htm (See New GM Secret Warranties, use the above "pistonslap" link to avoid some pop ups (skip the tripod link)). http://www.motortrend.com/buyersguid...0208_corvette/ (defective build quality concept).
In cases where a re-ring / piston replacement is required, have an independant engine expert examine the block for cylinder wall scoring to see if the engine should be replaced.
Ford had similar problems and replaced the engines with new ones (from the piston slap link above).
