I've read that and since I have a manual trans I'll just avoid eco mode. I purposely didn't try it after reading all the stories during my pre purchase research. I almost took it out and cycled in and out of eco to see if the lifter would reset for the hell of it but I'm leaving it be.

It's runs great! Did a full teardown, replaced everything oil touched including the dry sump system. Comped me the Platinum GMEPP for an additional 3/36 bumper to bumper too. Noting like a 2016 car with B2B warranty through mid year 2022
Other than the stress/worry of a new car having this issue, It was a positive end result and I'm happy with the level of service the dealer provided.

Finding a good C7 Tech is not easy. There is a small dealer in Hartsville SC where I picked up my Grand Sport bought with Courtesy Delivery who has a great C7 Tech but not sure I would not try to find a larger dealer. Got my 2014 from Hendrick in Cary NC. They sell a lot of Vettes. Don't know much about Hendrick in Charlotte.

That noise is NOT a lifter IMO sounds like an exhaust leak or pipe hitting something. Early on (2013/2014) there were a few posts about the insulation in the valley cover out of place and making a loud injector pump noise BUT I have not heard anything like a that in my 2014 or Grand Sport LT1.

Jacking the wheel and turning was no help even when lifting only a ¼ inch off the pavement, no noise. Tried the GM suggested, “remove the wheel and clean the matting surface” and retorque the lug nuts several times. Even trimmed some plastic I thought was offending. No help but the noise became less.
When I changed oil at ~1 year I saw the problem, which by then was almost gone. A wheel weight was on the inner edge and had been warn slightly on the front and top edge. Obviously, it was hitting the plastic brake cooling duct air diverter! A spot on the diverter and the top edge of the wheel weight were wearing! It’s gone now!

From inside the car I would bet money it was an exhaust leak from the passenger header collector or midpipe but standing over the motor with the hood up it's obvious it's on top of the motor. I would have opened it up myself yesterday if it weren't under warranty. I'll keep you guys posted could be a simple fix I definitely could be wrong. I'd be thrilled if I were haha.

No not normal. I’m not trying to turn this around on you (sincerely) but how did you not hear that before ou bought it. I always doa thorough walk around, and check the engine while running. Did it present after delivery?

Try using a piece of hose as a stethoscope and check around the bottom of the manifold. In 2013/2014 that is where, as I recall, the sound insulation under the manifold to muffel the ~3000 pst mechanical pump noise was found out of place. Also check the stainless cover on the exhaust manifold.

I bought it remotely from a forum trusted dealer. I did not hear it run until it was being backed off the enclosed carrier and I noticed it immediately. At that point it's mine like it or not. I sincerely thought it was an exhaust leak I only realized later something more serious could be going on. Even if I had I can't tell the truck driver to take it back, I owned it. So what's done is done.

For sure. Truth is no one even knows the problem but there are likely suspects ranging from minor to major. On top of that no one including the selling dealer, the local guys or gm corporate is even aware or had the chance to address whatever it happens to be. I'll take it one step at a time.

The dealer who sent you this car must have heard that ticking when they shipped it to you. Hold them accountable - and if they don't make it right, let us know what dealer sent you the car with an obvious engine tick. Hopefully it's something minor but that sounds bad to me.

Sorry to hear bout this issue. Any LT1 owner will tell you that is not normal. I have an M7 with 19K miles, and mine doesn't idle like that.
Just thinking out loud... I assume you are still on first tank of gas tank. But even if the dealer put low octane complimentary fill up in there, knocking would affect all cylinders equally, and the sound is definitely near the rear two passenger side cylinders. Anyway, the knock sensor would have triggered a timing change, so that can't be it.
Good luck, we'll all curious what you find out.

Sorry to hear of your issue, let's hope resolution is minor as opposed to major. My experiences over the years have taught me it's best to never buy a car sight-unseen or in this case unheard. Surprised the selling dealer didn't hear this defect, if in fact they didn't.
Good luck OP. Hope it turns out to be minor & you get to enjoy that new ride soon.

That sounds awfully familiar, sorry you're having to deal with this. This was my failed lifter... they ended up doing a complete rebuild.
