WOW - yeah - that's no DI tick... Sorry about your delivery issue - but interested to hear where this goes. I know the selling dealer isn't on the hook for anything cause like you said it was yours... but - have you at least contacted them to let them know / weigh in on things?

 

This does not help the OP but may help others.

This is why I tell my fellow members do not pay for the car or sign the paperwork until AFTER fully inspecting the car. When I factory ordered mine from a forum dealer the car shipped from the Bowling Green factory to my local Chevrolet dealer. After they and I did a three plus hour inspection did I overnight the signed paperwork and wire them the money.

 

I informed the sales rep I purchased from and was told that no problem was noticed during prep. He asked that I keep him informed of what develops. I haven't asked for anything and nothing has been offered. Just have to wait and see how things develop I'm not assuming anything good or bad at this point.

 

Assuming the dealer has now looked into the car’s issues, what new info is there to be gleaned from this tick issue?!

 

My late MY 2018 has always had a tick like that, especially when the engine is cold. Always assumed it was the fuel injection because that was the way my 2011 Mustang V6 sounded. Hasn't changed at all over the past year and miles.

What I would like to ask is whether in your opinion, the tick in the videos is more accentuated or prominent than when you are hearing it in real life? The reason I ask, is because if in real life it is not as loud as in the video, then it is probably normal. Unless I too have an issue

 

It's pretty loud when cold you don't even have to try to hear it. It sounds like a large exhaust leak when driving and you can hear it inside the car with the radio at a normal volume and the AC on. It was loud enough to me I took it in. It is a loud sharp metallic ticking. Think if you had a hammer and we're tapping it on a metal surface. It's sharp and loud.

Verdict is a bad lifter on the passenger side. All lifters are being replaced on the passenger bank. The warranty is covering the work of course. Should have the car back by Friday I'll check in whether it resolves the issue or not. Servicing dealer was very forthright and helpful in getting it handled no questions asked.

 

^^^^ Read above ^^^^

 

Is the servicing dealer also the Courtesy Delivery dealer?

 

That diagnoses makes sense to me. Glad to hear they’ve identified it and are addressing it. Keep us posted.

 

Sure thing Dad

 

Hopefully the dealer will fix the problem for you and you can enjoy the car.

 

Excellent, glad to hear that they got it diagnosed and it's early. Sounded lifter-ish to me initially too (albeit nowhere near as loud as the other dude).

 

This is the same sound but louder that mine makes, louder in drive than reverse, and it buggggs the hell out of me. It hasn't gotten worse for me, bought with 8k and now have 13k on it, so I just try to ignore it. Still buggggs me. lol Glad you got your noise fixed though.

 

Awesome, glad they got it figured out.

Curious if they mentioned which one, was it the #7 like mine?

 

Picked it up this morning. They did an "extreme road test" to attempt to dislodge any debris that could be causing the problem per some technical order. That didn't work so they replaced all lifters. Techs reported no obvious damage or failure so they can't tell me what lifter it was. The low miles worked in my favor there I suppose.

I looked it over well enough to be on my way I'll check it over more thoroughly tomorrow when I have time for it to make sure nothing small got missed. What I can say is the noise is eliminated for sure no more tapping just the low whirring sort of noise you get with the direct injection that I would expect. I can take a video to compare if people think it'd be useful data to have a before/after.

I'm very pleased with the service I received. It took them one day to diagnose and repair it. It was ready yesterday afternoon, I dropped it off the morning before. As far as GM corporate goes I've got some concerns I'd like addressed with them so I'll be contacting customer service but the servicing dealer was top notch in my book. They took very good care of me.

 

Selling, Courtesy Delivery, and Servicing dealers?

 

As I said before there was no courtesy dealer. The circumstances of delivery are in the thread feel free to read it.

I am happy with the service of the selling dealer. The business end of things was handled well and they were in the loop on the status of the repair. I give them the benefit of the doubt on it. Even though it only had 50 miles on it when I took it in 90% of that was me driving and it is reasonable to believe that the noise got worse in my possession. It may have been undetectable to the average person when it went on the truck at their end or could have easily been written off as the high end of normal. I don't know, I wasn't there. There were no obvious in your face warnings or damage for the average person to notice. It's not like they sold me a car with a service warning or no oil in the sump or a misfire or whatever. Maybe I'm too easy going with it I dunno. In my line of work I am constantly inspecting and evaluating all types of mechanical equipment so I am also particularly sensitive to noise, sound, smell, etc. when it comes to these things.

My advice is the same as what others have said. Pick your cars up in person a defect could exist on any car from the factory regardless of who the dealer is. Otherwise I wouldn't modify my process. I'd buy another from the same place without a problem. I'd just go see it first. I won't be mentioning them by name as I'm not upset with them and internet forums have a tendency to overreact, no offense. The advice is if you are buying remotely, inspect personally.

Servicing dealer was Love Chevy in Columbia, SC. They handled the problem very well and they were very apologetic for the issue I was having so soon in my ownership. Didn't care I didn't buy from them, didn't rake me over the coals attempting to assign blame for the problem, just said yep I hear it too we'll check it out and a couple hours later they were in it replacing and repairing no questions asked.

In both cases I have a single experience to draw upon from both the selling and servicing dealer it ultimately means nothing in the big picture. Although I am happy the car is fixed and can now focus on enjoying it.

Thanks for the help and commentary all.

 

Hey if you get the chance post a vid of the fixed engine running, I'd like to hear it.

 

AND thank YOU for your timely, concise, and succinct explanations and progress reports. Some of the best I have ever read on CF for a start to finish denouement!

You were accurate in correcting me...... as I was cross-thinking of another similar CF thread that involved a Courtesy Delivery.

Now you can begin to enjoy your new purchase!!!

Hopefully no more shop time during your ownership.

You gotta “love” Love!

 

For the sake of comparison I'll put two of the original videos here along with two similar ones post-repair. As you can tell from the videos the tick has been eliminated and all you can hear is the normal "sewing machine" type of noise you'd expect from the DI top end.

As a side note does anyone know whether the lower little legs on the engine cover pieces are meant to rest on top of the coil covers or tuck under them? Seem to be two little spots for them to hook under but I don't remember how they go back on and they were installed resting on top when I got it.

I hope someone can benefit from this thread in the future. I'll document whatever else happens that is relevant. Thanks.
