Sound like dealer has been BSing you long enought. If I were I'd ask for a new engine.

 

Both.

If you do plan to keep the car for a long time then I would want to be sure that the issue with this motor is really fixed. This is a high performance motor that is going to be revved high quite often. I would not want excessive bearing clearances or possible cylinder damage & blow-by.

I would not surprise me if they could pull a rod with the motor in the car, but if this was my car and I would prefer a complete inspection. I am not sure if the dealer would actually comply with this request. It would be a shame for them to swap a piston assembly with the motor still in the car and then have the car come back with additional problems. Hope it work out with as little hassle as possible. I would do this: :)

Mechanical problems can be difficult for a dealership to diagnose, just like any other modern engine malady. You can't generalize, and state that it should be easy to spot by the dealership.

Dealerships today have a tough time getting good mechanics :conehead: to service cars.

An owner of a Vette shares the responsibility of giving the dealership accurate information about the car, specifically what is perceived to be the problem. Patience is necessary for the customer service relationship to work properly.

Z06's offer a tremendous envelope of performance for the price, and to expect a 'perfect' unbreakable car, along with a fantastic value is not being reasonable. :banghead: The warranty payback given to dealerships barely covers the overhead of running a shop, and this is not the dealership’s fault. It’s not GM’s fault either, considering what you get for the small amount you pay.

I think it's high time we all start having some fun with are outrageously fast and Z06's and not expecting the dealership to fix every little 'tick' or squeaky noise that offends us.

You get what you pay for, and with a Z06, you should be glad that Chevy makes a car for that little money that performs the way is does.

Are you a GM public relationship person? Cuz you sound just like them: We sold you a perfectly good car for cheap, you broke it, why do you expect us for fix it?

 

I'm sorry but $50,000 isnt exactly chump change, they should be able to make a car without these kind of problems. Most owners think the same way. Everybody know's nothing is going to be perfect the only way it could be near perfect is if NASA were to build it, and if they were to, it would cost about 200K, and they would only produce about 10 a month, but come on there is absolutly no reason for this kind of problem. For 50k you shouldnt have any problems like this, the only problem should be going through rear tires! :cheers:
Jonh i hope everything works out for you, were all pulling for you! :yesnod:

What are you - kidding me, right? I sure hope so!

I notice this is your first post, and from your profile you don't own a Z06 - nothing wrong with that, and a 67 isn't bad.

Before you came here acting like a disfunctional marketing apologist for GM, did you even BOTHER to listen to the audio of his engine? It sounded like a friggin Singer sewing machine. Maybe next time take some time to investigate before coming in here preaching.

Welcome to the board BTW.

With all due respect, this is the goofiest post I've read in a long time. Remember, part of the purchase price pays GM to support the car. They charged us to support it...they don't "give" a warranty out of the goodness of their heart.

:rolleyes:

I agree that GM should fix this. John will just have to have some trust in his dealer. Hopefully they will make things right.

 

I'm not oozing with money but I would offer the service manager to pay for a teardown to inspect the engine just so I could sleep at nite. If you can convince him to pull the engine under warranty, with the understanding you will pay time for the inspection, who knows what will happen.
Basically I don't mind paying to get satisfaction. Most guys know this and I do alright. I tip my mechanic and treat everyone with respect. I think your handling this with a lot of class. Good luck

 

rb and any engine experts:

The GM rep stated that the problem won't get any worse, nor will it create additional problems. They stated that they are so sure of this that they offered an extended warranty to leave the car as is. What are your thoughts on this?

 

If you leave it as is, the noise will drive you nuts. It's all you will hear. Get it fixed. The wrist pin is pressed in and most likely has not harmed the cylinder wall.

:cheers:

 

Les, thanks for the welcome.

I listened to the engine noise, and apparently it was something of a serious nature, but often times it's just plain NOT.

It makes me :U when I see owners complaining and crying about the best Corvette ever manufactured.

I think this :cry baby stuff comes from feeling out of control and not being to fix the problem personally. :nopity If you want an easy fix that's in your control buy an old vintage car, or just stick a sock in it.

You benefit from the new Z06's high science, but there is bound to be an occasional minor problem.

How do you thing a guy with a $100,000 Porsche feels when his car acts up?
A lot worse. :cuss

The Z06 is a bona fide super car, better performance than most exotics, and you get what you pay for. 5 years ago you would have to pay much, much more to get even close. Don't complain too much, or it might just change :( AND BECOME EXPENSIVE, DUE TO ALL THE OWNER WHINING

Since when is any car, Exotic or otherwise, with the level of performance exhibited by the Z06 99% reliable? Name one :rolleyes:

The only true guarantee’s you have is that when the car is running OK, it's a great one. Everyone who paid $50k for that car STOLD IT ! I truly believe this :chevy

God BLESS THE USA, CHEVY, and the new Z06 :flag !!!!

BREWTWO,

Thanks.

Calling my post goofy must be your way of welcoming my ideas to the board.
:cheers:

I consider it a great honor when someone with your stature engages in a serious discussion, and is compelled to refer to my statements as goofy as part of their carefully crafted response. :yawn:

 

This is really a judgement call that I cannot help you with. If you can live with it and the car dynos at what the other Z06 cars in your are dyno then I might be inclined to accept the extended warranty and leave the car for now. If it gets worse bring it in for sure.

From here in front of my keyboard I really cannot help with this decision. I would need to see the car and compare it to mine. Good luck.

John, dont pay attention to that person, 99% of everyone on this forum would know that, that noise wasnt normal and would try to figure out what it was and have it fixed that person being the 1% who wouldnt! And as far as them offering you the extended warrenty, i dont know if i would go for that because what if they dont want to service your waranty when something does end up happening and plus that noise would drive me insane, not to mention resale might not be as good, with that noise that is. This situation is really not something that any of us would like to be in. I guess if i were you i would have to let them fix it, but make sure you go over your car with the manager, or GM so that way they wont scratch it up and say that it was there. What ever you do i wish you the best of luck. :cheers:

 

You may want to look at this. It is not a TSB, but a preliminary finding...

Engine Knock on Startup (including Hot Re-Starts) on LS1 V8 Engine #PI00150 - (02/12/2003)
Engine Knock on Startup (including Hot Re-starts) on LS1 V8 Engine
.

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
Engine knock on startup (including hot re-starts) on LS1 V8 engines built after April of 2001

Recommendation/Instructions:
Determine if a piston is making the noise by shorting out the fuel injectors to individual cylinders. After determining which cylinders are the source of the knock noise (90% of the time it should be #1) eight standard size pistons may be ordered through SPO.

These pistons should be measured with the largest piston going in the noisy bore, and the next largest going into #1 bore and #8 bore, in that order. If measuring equipment is unavailable, most machine shops should have the capability of determining piston size.

The new piston will come with rings, but they are not to be used. The rings should be removed from the old piston, and install on new piston in the position they were removed to prevent oil consumption. Do NOT dress the bores! Care should be taken to assure the old rings are re-installed in the same position in the same bores as they came out of. Document ID 195097 describes the piston and connecting rod assemble procedure which requires the use of heat during dis-assembly and re-assembly. HEAT MUST BE USED DURING DIS- ASSEMBLY AND RE- ASSEMBLY TO PREVENT PISTON DAMAGE and/or rod distortion.

 

Well, are you interested trading up to a new Z06? I wouldn't leave it ticking unless you were planning on a trade in next year or whenever. Be sure that by accepting the warranty that you arn't also accepting that the noise is "normal".

 

J-Rod,

Thanks for the info. C5-TECH posted the same info in another thread. Isn't that for a piston slap issue? The engine noise in this case continues, even after start up (it's a continuous noise that does not go away). They also said it was the #8 cylinder. Perhaps as rb said, the engine needs to come out to find out what is really going on?

 

Polar,
So let me get this straight ,Pay $50k for a car with a warrantee that ticks like a diesel ford pickup truck and your answer is 'dealers have a hard time getting good mechanics' :nopity AND 'u have to be patient"? :lol: Go back and read the history of what our friends' been through w/ this car! A baker's dozen trips to the dealer to be told" come back when it gets worse?" :smash: .U r an apologist for a dispicable business practice; let me guess, your also volunteering as a human shield in Iraq-who just left to return to his socialist homeland because u realized that u might be taken advantage.APOLOGIST- isn't anyone responsible for anything they say,do or sell w/ a warrantee anymore? :cuss :nono:

Since when did a ticking engine become a NIGHTMARE :confused: The solid lifter cammed, fulie 327's in Stingrays ticks like there is no tomorrow. Does that mean that the engine should be pulled :lol:

Since when did the car buying public become such wimps that everything has to be perfect ? all the time ? You get what you pay for with the Z06, and then some.

Chronic complaining and whining will not bring your emasculated manhood back. :nonod:

I won't apologize for wanting the car buying public to get what they asked for... a great car. The Z06 is just that, and inexpensive too ! What a bargain ! For 50k you get a car that can beat just about anything on the road, and looks beautiful too.

A warranty is supposed to cover Manufacturing Defects, not every thing that goes wrong with a car ( a potentially abused one ) is the MANUFACTURERS FAULT !!!

Some people think a warranty is their ticket to Beat the crap out of their Vette, over-rev the motor, and just have someone fix it when it breaks.... Just like THAT ! The rest of us end up paying for the extra cost imposed on the dealership due to some buffoon's disgusting and reckless behavior.

Our current government trough feeding, dumbed down, hip hop, gansta', welfare driven culture is always looking for SOMEONE TO BLAME ! Makes me :U

A little 'tick' never hurt anyone. I drove and race a Chevelle with a LOUD tick for 50,000 miles until I sold it, and got more than I paid.

I suggest that anyone excessively bothered by a little 'ticking' noise in their engine do one of three things: 1.) Check in your wife or girlfriends purse to find your stones, they are missing. 2.) Enroll in a ceramics, yoga, sensitivity, or crocheting class. 3.) TAKE THE BUS !
