The issue: Engine ticking, one sided. 2008 46k

Actions taken: dealership visits, 4 to be exact within the last 3 months. I have searched and searched this forum, however I rarely found a thread with a solution which is why I made this one. There has been no noticeable decrease in performance.

Dealer comments: cannot duplicate issue or cannot hear noise. Tricia from Chevy Customer Service on here was nice enough to get involved last month and kick-start a process with dealers. After a few calls from service managers and GM reps, I was told if dealers cannot replicate the concern then nothing can take place, which is understandable, but aggravating. My first concern was a high pitched "jingle/ping/rattle" that is still there but as the engine warms up now I have developed this "ticking" sound. So here's the vids: I'll be heading to a performance shop in Nashville tomorrow to get an "outside perspective." In person, it almost sounds like a "striking" sound instead of a tick so who knows.

My concern: Is this normal? Why is it only on one side? Why does it only occur once the oil is warm? Just curious as to what other forum members may/may not be experiencing with their Vettes.

Hood up


wheel well

 

Exactly !! Mine has a tick its driving me nuts.Is it the Fuel Pump ????

 

This might sound a little goofy, but...
I have owned a few motorcycles and when I would hear something out of the ordinary, I would listen to the motor with a modified stethescope.

Specifically, I removed the flat peice on the end (the thing that the doctor would place on your chest) and insert (screw) a long threaded bolt into the tube end.

Holding the bolt end against the engine in various areas allow's you to listen to specific areas of the engine. I have done this for years and it may not tell you exactly what is going on, but you can certainly hear where the noise is coming from.

 

I bought a mechanics stethoscope from Auto Zone but unfortunately I am still unable to pinpoint the noise

 

Mine is on the Drivers side also !! I hear it when I pull into the garage.

 

Same here. My 09 with 6500 miles has the same thing. I can hear it best when at a drive-through or when I pull into the garage and the sound bounces off a wall. It's tough to hear with the hood open. I don't notice any issues with performance so I am not that concerned. Should I/we be?

 

May I ask what year/mileage? It's quite annoying to feel like your engine may blow at any given moment.


Is your's one sided also? Curious myself as to if it may be normal as this is my first American V8 engine.

 

It is a common noise with LS motors. VERY common.

Our cars are often related to sewing machines from valvetrain, injector, and other noises from under the hood. It is massively worse when you start adding things like headers and intake manifolds.

 

I don't claim to be any expert but I don't hear anything I'd consider abnormal. If you're still concerned keep trying to find the exact source of the noise you hear. If the dealership doesn't think there's a problem find a quality independent mechanic to work with. My engine sounds way different. I actually had one guy come up to me (quite excited) telling me I needed to add motor oil ASAP. I assured him the engine was fine. He didn't know I spent a lot of money so my engine would sound that way.

....not goofy at all!

Mechanic's often use a stethoscope with a long, thin, metal rod attached to help pinpoint mysterious noises. When something was rattling underneath my car we used a stethoscope (with listening rod) to pinpoint exactly where the noise was coming from. In my case something broke-loose inside one of my 2-stage, aftermarket cats.

 

2008 Vert !! 27k miles,only on Driver'side.

 

Yes, I hear a slight tick. I assume it is normal valve train noise. (My 5.7 Dodge Ram has a similar sound, tnhough I don't notice it on my wife's Charger with the same 5.7.?) I did the DIY muffler modification, hoping more exhaust noise would hide it. No such luck. Just living with it.

 

Mine ticks like a typwriter. It is most noticable at around 1500 RPM at steady light throttle. I took it to the dealer at 6K miles, the dealer agreed it didn't sound right, stripped down the top end and examine the valve train, and replaced all eight lifters on one bank.

When I got the car back, it still ticked, to me it sounded the same as before, but the dealer insisted is all normal. I don't worry about it

 

 

So GM can't make an engine that doesn't tick ??????????????????????

 

This. My 2004 LS1 had a tick the entire time...noticed it most on start up. My 2000 LS1 didnt tick quite as bad. My 2012 has the same tick as 99% of the LS engines I have ever heard. Nothing major, just a slight tick. Dont worry, its not going to blow up. I would be more worried if I had one that didnt make a ticking sound. My fathers 5.3 (yes, I know not quite the same) in his 2011 GMC ticks as well just like my friends 02 T/A does the same.

If you want to hear ticking listen to TL1000S/R engine. TL = TICKS LOUDLY! lol

This is true.

My friends 78 LM1 Firebird had a tick. We adjusted the rocker arms and got 90% of it. Changed to a thicker oil and it went away. The engine in my 69 camaro ticked, as did my L83 and LT1 Corvettes. haha

Most rebuilds even have a tick from my experience.

 

No expert, but sounds normal for a performace V8.

 

Every time my wife rides with me she complains that it sounds like "chains rattling" under the hood.
She swears I got ripped off on the used Corsa exhaust I bought to swap out the Stingers that were on there.
I tried to explain that with the headers and intake, it's normal.
She's not buying it.
I have to agree, it does sounds very crude.
At WOT, it sounds great, but part throttle, very noisy!

I'm taking it in to a local performance shop tomorrow to have them check the whole exhaust system, from Vararam to Corsa.
If nothing's leaking, then that's just how it'll be.

I also notice a loud metallic clank when I shut it down.
I've never had a car with headers, intake, etc, so I'm not familiar with what's right.
It's been running fine for 8000 miles since I got it in November, so I chalk it up to normal.

Now on my 2011 5.0 Mustang I traded in for the Vette, that had a tick.
It was at the dealer for a week while they performed a TSB on it.
Cam tensioner or something like that.
Quieted it down, but I traded it immediately after.

 

Every LS engined car I've ever driven, including the three vettes I've owned (C6 LS2, C6Z, C6 LS3) all make this noise, as well as the "sewing machine" noise at around 1800 rpm.

I'm pretty sure it's normal valvetrain noise.

Do what I do when my wife has a comment about the noises, run it up to the red line in first and second. After that she usually doesn't say another word the rest of the ride.

 

Yeah sounds pretty similar to "HEMI TICK"
