I had GM install new rings on my 2001 Z06 at 9,900 miles (it was using a quart for every 500-600 miles) & it needed a quart after the first 1,000 miles (not going over 3,000 rpm). The service manager said I should be getting at least 1,500-1,700 miles per quart & asked me to give it more time. I just put another 900 miles (not going over 4,000 rpm) & it needs another quart of oil. I would appreciate anyone's suggestions.
Thanks,

IMHO, take it back and tell them to fix it correctly. Others with oil usage problem have had this fix, and are pleased with the result. C4C5Specialist, where are ya???

Take it back

Hi there,
I do agree that the car must be taken back, and have it checked.
I am sorry that you have had such problems. I do NOT have an explanation for this.
Please keep me posted, c4c5

I'm going to take it back to the dealer this Monday & see what the service manager wants to do. I was hoping the new rings would solve the problem.
Thanks,
Bob

Hello all,

Will GM fix the ring for free? My Z06 arrived on 04/01. How do I check that I still have a problem with the ring? Do you folks have the link or information to this problem from the official site of GM or Chevy?

Thank you,
Tambeng

Tambeng--
I'm not sure what GM is going to do, but I will talk to the service manager on Monday. GM considers excessive oil consumption if you need a quart of oil for anything less than 1,000 miles & they usually won't do an oil consumption test, unless you have at least 5,000 miles.

Possibilities

Well, if I may,
It could be that someone broke a ring while they were putting it in. Due to the new design, it is VERY easy to snap the outside ring edge right off. And yes, I am speaking from experience.
As for the repair, my guess is that the ring gaps may be off, or that there are a few broken ones.
I dont know, but under a normal repair, the rings would do the job.
I am taking picures of the one I am doing now, and will post the findings so you all can see the difference.
Besttoall, c4c5

I would appreciate any photos, or information. I will forward it to the mechanic who will be working on my car, when I bring it back to the dealer.
Thanks,
Bob

c4c5.............???????

Question, in the article I noted above in this thread.......Juriga stated that they "Might", change out PISTON ASSY's.....instead of JUST rings......

I would think, for this same reason......

As Tech's, you of course would have to still make sure the ring gaps were staggered properly before assembly......but this fix, would eliminate close to 100% the chance of a broken ring/s......

Have you / did you hear of this approach being discarded or anything to validate same?????.

Thanks:)

As to the horsepower-- I belive the horsepower was increased, as my car feels more powerful since the new rings were installed.

You should have, as much oil as you were losing HAD to have caused you to lose some compression.......

Oil Consumption Article

Let me say this about the article, it appears to be more marketing and damage control than an accurate description of the problem. I got my Z06 in February '01 and first experienced oil consumption problems in March '01. No one ever contacted me to ask about my driving habits. I do not run my engine at high-rpm in light-load situations and I burned a quart every 500 miles until I had the newly designed rings installed. I always shift at 3,000 rpm, always, with very few exceptions! John Juriga mentions people driving around twon at 4,000 rpm or over with partial throttle. Those are not my driving habits. My mileage is split fairly evenly between stop and go city driving and highway mileage at highway speeds, but I always keep the rpms to 3,000 or below before I shift. Does anyone out there with this problem drive their Z06's around town at 4,000 rpm or above on a regular basis?
