My automatic car has 10,000 miles and was burning 1 quart of oil every 1,500 miles in low rpm city driving. They replaced the rings and now the engine is leaking oil on the garage floor and is running rough and continuing to burn oil.

 

What would we ever do without lawyers ;)

 

1 qt every 1,500 - 2,000 miles. It seems to be getting better with 6k on the car now.

 

That's a bummer. I am assuming from your original post on this thread that you are trying to lemon law the car... BTW, thanks for that email.

I am hesitant to let the dealer tear down the motor to put new rings. Do you need to let them have a crack at it before filing with BBB or should I file with BBB....I don't want to kill my relationship with the dealership, the service manager there knows a lot about the C5 and has been helpful to me through the years.

What are your plans for this car?

Later,

 

This is not intended as a flame....

I understand your frustration, but truthfully, most of the 2001 cars don't burn excessive amounts of oil and most (not all) of the folks who've had the repairs done were satisfied. In addition, the repair, though time consuming, is not all that difficult to complete (some techs don't even remove the engine for the ring swap). Sure, there are exceptions, but that's what the BBB and Lemon Laws are for.

 

Ben, you're so right...the first thing I have to clean after taking a quick spin my C5 are the exhaust tips. I usually put on about 3,500 miles a year and with two oil changes I've noted about a total loss of about a quart (or a half quart with each oil change).
My '94 never burned a drop!

 

Born May 25th 2001, 2500 miles maybe a pint down, I don't baby it at all ask my wife, getting ready to change soon.

 

Just a thought...I know the owners manual states to wait a few minutes before checking the oil. It is possible due to different internal temperatures that the oil dripping back to the pan returns in different amounts at different rates. I wonder if folks once in awhile get a false low reading then add oil only to not know they over filled and then it blows out fast leading them to believe they used it? For what its worth I only check my oil after the car sits overnight. It has stayed on full or nearly full for the first 1200 miles.

 

Thers a million theories who can you trust and the bottom line is you paid 50k+ for a car way above the cost of yor average Chevy and they get conflicting info and now a ring swap maybe from a tech who works mostly on trucks and Cavalliers.I want to be ATTENDED to when I buy a HI dollar car.If it were a BMW 318 for 29,000 they would treat you like a M3/5 buyer and they would fix it right the 1st time.and it would be clean and sparkling.
When my 01 Z06 was bone stock and FUN,FUN,FUN I was loosing a Qt. every 4-600miles at 6,000 had a LPE stage2 TT kit done broke it in like a bank robber from day 1 and wouldnt you know it my HI-PO Chrome molies made no differance At 4500 miles I was averaging 1 Qt. every 4-500 miles I lived with low oil warnings and this motor was built tight mostly by Ed,he has to be (being Johns master assembler) Ed has built some of the fastest motors on earth!!!!.
I trust LPE who pretty much designed the LS6 and they rigged up a new PCV system and paid for a local shop to do the install.Well guess what I went 2400 miles VERY HARD power shifting 200 mph+ miles and I didnt burn a drop 0 NADA.They will only sell this to LPE buyers from what I understand it has to do with a top secret legal GM deal as you know John does alot of R&D and design work for GM and even though its noy well known I know about it and he makes a whopping 30-40 per hour for an engineering staff its a money loosing deal but they make it up in other ways.
I've since upgraded to a C5R TT with adjustable boost and not only is it so fast its crazy but I see all the strokers out there and we at XTREME Like LPE dont advertise to much but our C5r's are the cats meow and were going to start racing some of them as soon as we have time that C5R is trully bullet proof and the block that GM builds is truly a work of art.We have some nice surprises for hp freaks (arent we all) and we hope to satify your HP needs beyond your wildest dreams and give you a product that is pleasent to drive to church and buy goceries with as well.A great weekend to all and drive safe but do it really fast.David Smilovic

 

22,000 miles on 01 Z06-burns no oil as long as i stay off the track--when on the track it throws it by the galllon.The car built before mine has had a engine replacement because of oil usage.I believe something in the 10-20% range are oil burners(just a guess)Add in the problems with oil pumps , scored cylinders and needle bearings falling out of the rockers--just not acceptable at all!!

 

GM admitts that there is a "generic" problem with all of the '01 engines- they had redesigned the rings, and those rings will develop a flutter if driven above 3,200 rpm under light load. That allows oil bypass/high consumption. For most people, avoiding the 3,200+/light load condition is the easiest solution, and that is why a A4 left in "D" will seldom have the problem- it upshifts automatically. For those folks who want to run any rpm/load combo, the rering job ususlly works.

My car with the A4 was burning about a qt every 2,000 at first, but it's dropped off a lot as the miles build up. Last Fall (starting at 17,000 miles) we went on a long road trip, drove the car pretty hard, burned 1 qt of Mobil-1 10W-30 in 4,500 miles. Not perfect, but I can easily live with that.

But there will always be a few cars with other problems that will need different work.

 

'01 Z06. Burning 1 QT every 800 miles. Have beautiful Daytona tip Corsas that get black as night in about 3 minutes. Really hate that...but am really afraid of tearing the engine down, even tho my dealler has done 6 re-rings with "good results"?. My car just broke into the 11's. 11.97 to be exact. Really hate to change things now. Could new PCV parts make a diff?

Wild Horzes,
Read this and see if engine temperature has an effect.

Clean your exhaust tips, then start your car and let the oil warm up to 190+ before taking it out. See if the exhaust tips are clean when you come back.

I'm curious if you will see the same results I did (on my 2001 Coupe).

 

Same here...... :)

My 2001 Z06 (delivered Feb 01) has always delivered more than 2000 miles per quart and it has 7600 miles now.

My 2001 burns about a quart every 2000 miles. :sad: Both dealer I purchased from and a couple of others have told me that is normal. :rolleyes: Now I am really wondering. :mad

 

According to GM, a quart every 2000 miles is normal. I'd be very happy if I got that on my 01 Z06.

 

My 2001 C5 MN6 Roadster is 13 months old and has 32K miles on it.

I toured the lower US for the entire month of April. The oil and filter were changed just before I started my trip and the DIC shows around 20% oil life after driving just short of 12K miles. The DIC told me to add a quart of oil at the 7K mark which I did. The message has not shown again after driving the last 5K miles to complete my trip. :yesnod:

On this trip I did not run the twisties hard and kept the cruising rpm around 1600-1800, 68-80 mph.

 

23500 miles on mine............i don,t beat it... i get 28/29 mpg and have never needed to add oil between changes(5k) that makes 5 times.. 1st one at 3k :)

 

Same here, only I'm at 4900 miles.
