I am loathe to spread or start rumors. But, I read on another forum that the LT4's are letting go (blowing up) at an alarming rate, and that GM is looking into it, and is holding/constraining Z06 and CTSV production as a result.
I have not heard any such thing (aside from the post mentioned above)....does anyone here have any 4-1-1 on this topic? I have read about the occasional failure here, and one of the magazines (MT, R&T?) blew one up during track testing....but it doesn't seem to be to be anything large scale. You would expect a few failures given the car, the drivers, and the test conditions....
(the title of this post is intentionally worded so as not to indicate trouble with the product since.....I do not think that there is any).
I don't think so. Seems like a low number given they built 10,000 by now. The Viper and GT3 engines however do seem to have lots of bottom end failures.

Sounds like something that you could read on Viper of Ford forums.
German sports car manufacturer Porsche has announced that it will replace the engines on every single 2014 model year GT3 sold--a full 785 vehicles. As recalls go, the correctional measures are fairly extreme--and is sure to cost Porsche a fortune, despite the relatively small number of vehicles involved--but could be the best way of curtailing further fire-related embarrassments for the company.
Personally:
I am loath to loathe; but,
you're kidding, right?
Well, no. It was from what I consider to be a credible source on a GM forum and I came here seeking confirmation or rebuttal. I am well aware of the reliability of information gleaned from the interweb so I came to seek information from other sources.
There should be nothing loathesome here. In fact I think a potential rumor has been killed before it started.
I will readily admit (unlike some others on the internet) that I do not know everything. Many comments on internet forums are worthless, but when there is a landslide of information one way or another, in many cases that implies a higher likelihood of correctness. Given the comments above which confirm my understanding, my reliable source is now considered to be a bit less reliable.
(in proofreading this post prior to submitting, it sounds completely dorky but I am not going to rethink or retype it......it's dorky but I think it gets the point across)
See the thing is that we have to take your word for it that a "credible source" has statistics that show the LT4 "blowing up" at an "alarming rate" that is causing GM to "constrain production". While a modest number of blown engines exist and are extremely well documented on this forum, there is no evidence (other than yours) that production has been in any way constrained. It would really be helpful to disclose your source so we can judge for ourselves.

We at the PBC in Bowling Green are holding to our normal build of 27 engines a day, on a 10 hour a day, 4 day a week schedule. Tonawanda, as I remember being told, build 137 engines a day on a 3 shift operation. So, no quality hold, no reduction in production, non issue. Major LT4/C7 hater BS.

Now THERE is a "credible" source Thanks Barry! My LT4 is waiting across the street and I look forward to many miles/years of service from it.

The volume that Corvette puts out for all Z06's of about 8,000 is roughly the equivalent of 8 days production in a typical car plant.....a years production in 8 days.....we are talking apples and oranges......

You guys are funny. I said "rumor." I said "I read it on the internet." If you consider that to be "evidence"......well, OK. I said nothing about evidence or stats. The rumor is debunked by what I consider to be "better information" here. Case closed.
Forgive me for seeking clarification and asking a simple question (which has been answered, and to those who answered, thank you); I thought that was what these forums are for. If you want to go hunt up the thread it was on a 2009-2015 CTS-V sub forum on the CadillacForums site, and it was from a member who, in my many years on that forum, seems to generally post positive and accurate statements about GM products, so it caught my eye. I am not going to go hunt up the link....

And there's your answer: someone who doesn't have one of the new Vs, spreading garbage about it. That seems somewhat familiar, for some odd reason.
Oh, and don't take what you read on the CadillacForums with anything but a massive bag of salt. They're... a bit special over there. As in the "short bus" kind.

This could describe every forum on the planet. I will defend that forum, like I would defend this one (though I have not been on here nearly as long). Like here, there are plenty of loose cannons over there, but there are plenty of very knowledgeable car guys who love GM, love their cars, and who know their cars very well. And many of them have 'vettes too and they respect the car and this forum. So...why bash the forum? My initial question was about one post from one guy. And....I purposely didn't initially quote the source because I did not want to invite such discussion. Silly me. I got suckered into it anyway.
Now, if you want to discuss the MustangForums......that is a whole nuther ball of wax......:-)
I think about 14 defective engines out of about 10,000 cars is not a really bad rate, even if none will be better ;-)
Yes sir I agree none would be better.
I think its closer to 8000ish cars/engines so far.
So if the number is 14 failures? That's a .2% failure rate thus far or 99.8 % of the engines are still good.
Anybody know what the industry average is for failures of new engine designs during the first year roll out?
Of course if its your car with the blown engine statistics are useless.
