Ok you send us to a google search page. Are we supposed search for your answer???

 

If you want to know bad enough it’s an easy google search and pretty common knowledge for anyone that has read even a little bit about the LT6.

 

Now that was a clever dodge. I own one. I have read a lot about LT6 The only article I have read that discussed the rockets said they were an interesting oddity. It ascribed no functionality. So if you know of functionality, please enlighten us on the forum. It would be very helpful. What I see in the rockets is an increased cost detail all over the place. I see on castings and machined parts. It provides some nice corners and edges that are characteristically stress risers. Not that GM would, but if there was a wall thickness that was marginal under some loading condition, the rocket says start the crack here. Maybe that's the functionality you are pointing to..

 

The rabbit holes the internet takes us down…..

You are right, you got me, there is no other purpose for the rockets except for Chevy engineers to **** off parts suppliers, make premature cracks in the motor and apparently to annoy you.

 

I agree, but that's what I was told by the service writer...

 

I noticed my Z turns on the fans almost as soon as I start it ( and it's not hot outside ) ..It's the first sports car I've seen doing this so I really don't know how he expects it to get that hot in the city or highway .. ... sorry to hear abut your engine , hopefully you get years of trouble-free fun

 

Update on my LT6 "ticking" problem:

Got the car back on Tuesday afternoon. First thing I did, of course, was start it up and walk around the car to see if there were any immediately visible traces of the major surgery, any "scars" or "stitches" if you will indulge me in my mechanical metaphor. First thing - no audible unusual "ticking", no audible trace of the issue before the "surgery". I let it warm up while I did my walk-around - still was sounding OK - so I "signed ze paperzzzss" and drove it home the long way, stopping to do a couple errands, and discovered that any of the GPS-related apps on the Infotainment thingy weren't working - they just were giving me the "Biden Stare". Another 45 minutes of my life on the line with OnStar I'll never get back, but that's something for another thread. Yesterday, I finally made some time to wring the car out some, put almost 150 miles on it with mixed driving; nothing "too" aggressive, but some was "spirited". Got it home and it still sounds pretty good, the "ticking", to my hearing aided ears, is virtually gone, just the normal sounds you expect from a complicated motor like an LT6. Later this AM, I'll take some time to really look the car over, see if the Technician has lived up to his commitment to return the car in a condition such that I'll never know it was apart.

Anyway, short tape: I might be one of the lucky ones who got the "fix" and it got all the TSB related ticking to go away. At least for now, anyway. <Insert fingers crossed emoji here>

Oh, and by the way, on an unrelated item but I'm excited anyway, I got booked into the Ron Fellows C8 driving school offer for December. Can't wait.

 

My left bank "ticking" got reduced by 75% w/ the TSB procedure- about 600 mi ago. Still OK- can barely notice, if at all.

Went last year for the Stingray race class ('23 purchase) and loved it, going back in 2 weeks for the Z06 class ('24 purchase)...Prolly be 200 degrees out, but I don't care;- cars run w/ AC full-on...

 

Update...Got my car back with new engine 2 weeks to the day. Thank you City Chevrolet!

 

 

Mine ticks a little bit when I get on it and get the RPMs up more aggressive and then when I go back to smoother driving it quiets down. Just sounds like DOHC noise to me when the pressures increase. Not uncommon. I have 3700 miles on it now and it drives wonderful.

 

Congrats 2Stroke, I think you were lucky being one of the 1st!

Unfortunately, my 24 Z06 just blew up at 30 days of ownership and 829 miles after being cautiously broken in. I was 240 miles from home and cruising at around 40mph in 4th when it happened without any warning! I was stranded in a puddle of oil with a chewed up intake valve and shiny little pieces of engine block to stare at! Just unfrekkinbelievable!

Got Onstar at least To send a tow truck, but the driver had to go back because he did not have the proper wheel dollies. And then we had a hell of a time getting it onto the flatbed since the wheel Dolly's were slightly too wide for the flat bed. A real nightmare story.

Next I had to get it towed to a certified Corvette Dealer in the area which turned out to be a very small rural dealer with virtually no Z06 experience. I was told to immediately contact GM customer care and open up a case file. GM tech has confirmed a total failure of the left cylinder head involving at least 3 valves, but they haven't torn it down yet. And since then I have asked if I can have the vehicle repurchased or replaced but I'm told not until the California lemon law applies. The engine and parts on backorder without any sort of eta plus I haven't authorized repairs yet until I find out if GM will tow it to a local dealer or it will cost me out of pocket in case it gets repaired in less than 30 days which I doubt is possible, but who really knows?

So my dilemma is to try and get it moved to an experienced/preferred local dealer so I can monitor repairs closely and in case they fix it in less than 30 days and I am stuck with it? Otherwise after 30 days I will hopefully be making 🍋 ade and get all of my investment/add ons back so I can start all over....makes me 😫 having to contemplate this inexcusable situation that GM puts it's customer in‼️

 

I feel for ya, brother! Hope this story has a happy ending for you.

 

Just- wow!
It's a hellova investment to go absolutely sour...
Please post updates.

 

Really sorry to hear it. While it sucks to wait, I wouldn’t worry about whether it will meet lemon. 8 months and counting here - GM still can’t figure out what’s wrong with mine. The engine replacement took almost 3 months, transmission cooler took another 2 months, new transmission took another 2 months, and the last month was spent scratching their heads and GM delaying looking at it again because the new transmission is still overheating.

Either I’m the minority and GM doesn’t care (certainly feels that way), or there are way more issues than we know about and they’re working a big backlog.

Either way, the chance of a new engine within a month is not very likely from my experience, but maybe you’ll get lucky.

That really, really sucks. Nothing worse than getting a brand new beautiful / expensive car and have it go boom.
Essentially they have 30 days to get a new engine installed and back to you or they have to re-purchase the vehicle. If it were me, I would be praying they don't get it back to me in time.
However, if they do, then you should negotiate some compensation (cash, extended B2B warranty, etc) for the fact that the vehicle will have diminished value because of the replaced engine.

Cal Law
The problem first occurred within 18 months of delivery or 18,000 miles (whichever comes first);If required by the warranty or owner’s manual, you notified the manufacturer about the problem; and

• You have taken the vehicle in for repair by the manufacturer or its agents:
  • Four or more times for the same problem and it still is not fixed, or
  • Two or more times for the same problem, if that problem is big enough to cause death or serious injury, and it still is not fixed, or
  • The vehicle has been out of service for repair for more than 30 days (the 30 days do not need to be in a row).

 

Wow so sorry, I wish luck on a speedy fix for this misfortune. When was your car built and the motor was built by who? As it can happen regardless who built it as pars sometimes fail. I wonder how that affects value as it will show on the carfax too.

 

How in all that is holy do you still own that car? I would have LL’d it after the 2nd month for sure.

 

Theres definitely something in the works. It’s comical at this point how terrible the service and warranty support has been on my car.
