'06 Quicksilver Z06

I have spent a good part of 4 days searching the archives of this great forum of ours to get to the bottom of how many actual members here with showroom stock LS7s have had them failed in Showroom bone stock C6 Z06s on this forum.

The Lineup after continual search beyond that initial search period, is below:

There have been 25,623 C6 Z06s built to date.


If anyone can find a post from the archives of another documented showroom stock C6 Z06, on this forum, which had it's engine fail, please point to the thread.

These are not reports from modded cars as with a modded car, all bets are off.

The car left Bowling Green stock. If it fails stock, then thats all I'm interested in finding out here.

Modded cars which fail, cars on sticky tires and/or suspension mods brake mods, on the track, GM is not at fault there.

The goal here is to find out how many SHOWROOM STOCK C6 Z06 failures we have seen on this forum and how that relates to the total number of Z06s built.

Bear in mind these are not people who say that they "heard of" one, I don't bother to list those because the one which someone "heard" about may be one of the ones included below.

The breakdown, no pun intended, goes like this:

Charles Scavone 2006 Model

whitjo 2006 Model

Bmore30 2007 Model

Joe_Planet 2008 Model

elh0102 2008 Model

dg144 2006 model

TFAST4U***** Owners does not state stock or modified, tracked or not, nor on what kind of rubber, nor the scenario or conditions under which the car failed that I could find.

66L72 2006 Model

I hope this puts to rest some of the paranoia, but somehow, I know that it won't.

Addendum: After a review of post #526 I am adding these 2.
*Pistol Champ Stock Failure added to list

*Codeblack Stock Failure added to List

*Re eval of Slim Shady

AMEN brotha.

cecil 07

right on.... been kinda worried about buying a used one.... but at .035% failure I can live with....

nice research...man, where were you when I had those research projects due in college.
Looks like a nice spread between 06-08 failures. But still very nominal compared to how many good running Zs out there.

'06 Quicksilver Z06

Again, I want to encourage those reading this to locate any other reports of completely bone stock cars on this forum which have had their engines fail.

These should be from the archives, because I am not interested in "manufactured cases" which tend to show up after a thread such as this one.

I'm also not interested in "My neighbor has a friend whose brother knows somebody whose barber has a nephew who had a bone stock LS7 fail" either.

Bone Stock, member in here, described up until now, 7/29/2009, and since the C6 Z06 came out. Find the threads or the post if I have missed one.

Thats all I'm interested in.

If you are modded, or pointing me to a modded car, I don't even want to know about it.

Nice writeup. Hopefully this puts things in perspective. Now we have facts that every other Z isn't blowing up.

I took my Z06 in for service today and my service advisor took me back in the shop and showed me a 2008 Z06 with a blown cylinder. Bone stock. GM is repairing it now. NOt sure if that person is on here but you can add one to your list.

smallblk400

Thanks for all your hardwork & time bro!!! Awesome to know & puts to rest alot of fears with our LS7 engines!

'06 Quicksilver Z06

Naw, I can't add that one to my list.

See above.

The threads in here give us a lot of information on the car. In many cases a whole lot. An entire history if you back search the person's posts.

Who knows if its bone stock, who knows if it was tracked on sticky tires, who knows if it was tuned, etc? The person who brought it in, may have told the dealer it was stock, and it may have been previously tuned, running R compound tires and pulling 1.5Gs in half a dozen 20 minute Group 4 HPDE sessions, who knows?

Or he may be on the up and up.

The owner is not in here to say one way or the other.

I am not saying that the 9 I have found are the only ones, there are no doubt others "out there".

But in here, we have 9. We are going to avoid the paranoia driving "hearsay" for this thread.

I only want to hear from the membership. The rest of the failures outside of here, are outside of here. And its anyone's guess as to how prevelant they are.

However the 9 that we have in here, OVER NEARLY A FOUR YEAR PERIOD ought to give one a notion that these are rare occurences

You are assuming that every Z06 from 06-09 ever sold are on this forum and these are the only failures.
At any rate, the percentage of failures "I am now assuming" isn't that much greater so buy with confidence.
Just don't mod the car in any way shape or form and don't track it. Just drive the 505hp monster on the public highways and enjoy. Geez I wonder how many folks would have purchased Z06's if GM had a marketing campaign like that

The owner of the car had nitrous, blew the motor, and had the nitrous system removed before towing to the dealer. Take him off the list.

longdaddy

good effort, but there are some issues with your math.

you need to compare number of failures reported with the number of c6Z owners registered here (and actually using this forum) if you want to have any claim to the validity of your percentages, not the number of cars produced by GM.

you are comparing apples to oranges at this point.


be careful injecting your personal opinions into your research, such as this one:

GM did cover some track failures and some failures where some of the mods you list were done, thus accepting responsibility, although the consistency is lacking.

by the way, doing a research to prove a point almost always produces exactly the result you want to see (which also happens to bear little or no scientific credibility)

Always doing your homework. Good job.

Good thread but I dont think you can say "9/25,623 represents 0.035% of all Z06s built" since not all 25,623 Z06 owners are on CF. If I miss read the your thread, Sorry.

I wish we could find out how many C6 Z06 owners are on CF.

Good thread, but a suggestion: add a seperate column or group for stock motor cars that failed (i.e. suspension mods, tires, etc but nothing done to the motor.) -Dan

ntrimm

I guess from that statement, you should take everyone off the list. Anyone could have done that. and like they would admit to it on here. TAKE EVERYONE OFF THE LIST. !!!!!!

383vett

You mean it's not 25,623?

'06 Quicksilver Z06

I knew that people would misunderstand this.

Actually I am not trying to figure an overall percentage.

I am trying to find a "Least" percentage if you will.

In other words, from the numbers gleaned in here, "at least" .035% of all bone stock Z06s have had their engines fail.

I am leaving it up to the reader to determine how many more on the outside other than the 9 in here, he believes there to be.

I am fully aware that not all 25,623 Z06 owners are on this forum.

However, that said, whatever the number of cars we have in here, 9 have failed.

9 out of that 25,623 over a 4 year period have presented in here.

How many more in addition to the nine we know about in here, do you suppose there are "out there"?

Bear in mind that about half of this nine failed on the track, and a good number of Z06s never see the track.

How many more "out there" do you expect on top of our 9?

Here is a hint. If there are 10 times more than our 9 in here, that would get you to 90.

I'll let you figure out 90/25,623.

Then try it with 100 times our 9 in here.

dbhajek

I am sure he is correct that there are 25,623 C6 Z06s. So you think all C6 Z06 owners post on Corvette Forum?

'06 Quicksilver Z06

This is not a scientific paper with the intent of submission to a peer reviewed professional journal.

These are just the number of cases REPORTED IN HERE. And what percentage of the total number of Z06s produced that number represents.

That is all.

If you can find other cars reported in here, then please point to them.
