All of this talk about tech's not wanting to do work blows my mind. A friend of mine was a Ford and GM tech and while he was paid a salary, he was also paid a "bonus" for every job he finished in less than book time.
Example, if GM paid 6 hours to replace lifters under warranty, and he completed it in 4 hours then he would get a percentage of the money for the extra 2 hours that the dealership was reimbursed for. He then went on to the next job, and again hoped to have the job finished quicker than GM's expected/allotted time.

Does this sound normal? Doesn't sound ok to me and I've only noticed it within the last few weeks/months. Mileage=35500.

Sounds like the fuel injectors doing their normal job.

The sound is noticeable now whereas before I never heard it. I hear it at drive throughs or when I'm next to a wall or anything solid. I've been checking it out for the last few days in different scenarios. It's definitely bothering me and it seems to be loudest after a rev of the engine.

I'll be taking it to the dealer but really hate to!

Mine has this same noise. Been bugging me a bit as well. Could be an exhaust leak in either case. (your or mine) My car has had the L99 lifter replaced with Z06 valvtrain parts with my cam swap. But if you have not had new headers or anything then it would be less likely.

Only changes made from the assembly line are muffler delete and K&N filter, non-cosmetic. It's really bugging the crap out of me, more and more daily! I just hate going to dealerships when not purchasing a vehicle, it always feels like a hassle, even when I'm paying for the service. Sad but true! I have 2 in close proximity(within 10 miles of eachother) and it's the same at both. I guess I just don't trust anyone with my car, with good reason! No one loves her like I do!

Aside from the sewing machine sound that I've been told is normal, I've heard (on mine) also what sound like a low-octave "click," as if you were to click your tongue only on the lower part of your mouth (if that makes sense). I've heard it a few times, tonight being the most noticeable since I could hear it from within the car.

At the next oil change I plan to mention this, but I'm pretty sure I'll be told it's normal (again).

Well I found my noise.

Kind of.

Meaning I narrowed it to one system.

When I turn my AC off the noise stops immediately. Turn the AC back on and it comes back on. Repeatable over and over again. My AC works sporadically anyway. So I suppose I'll have to have it fixed finally. AC not really a DIY thing. Sucks.

What year is your car? I distinctly remember a TSB on certain VIN numbers concerning AC units in our cars. 2010/2011 models only I believe. Becky at Rogers Chevrolet can check your VIN against the magic list of VIN's affected if you PM her your VIN#. I do know what you are talking about though. Mine does it as well and it's annoying but probably normal. Sounds like dry bearings spinning around when the AC kicks in. I don't use my AC unless I absolutely have to so I'm not overly worried about it at this point. Good luck either way!

Admittedly this is my first "sports" car. I've heard ticking from injectors on all my previous cars but never from inside the car nor standing beside it while its running. Hearing ticking in the cabin or standing outside the car with the hood closed, to me, isn't right. I could definitely be wrong but its bothersome to my ears. In my case it sounds like one or a couple of them are much louder with a different tone as well.

Mine was the first one of the first. #9067 so it's a 2010.

Was the TSB on just the noise or was it also the ac no blowing cold?

I can't remember exactly, just that it was A/C related.

Cool. Thanks. I'll check with Becky. I know there was and HVAC condensation leaking into the car issue.

Take a long screwdriver or even a broom handle and hold one to your ear and the put the other end in contact with some part of the motor and you can better hear what is going on. Move around to isolate the area where the noise is comming from. Just be carefull around the belts and rotating componants. They sell auto stethoscopes but this works just as well.

Took my lady in today for driver seat cover replacement and lifter issue. Apparently the guy that knows or does this type of work has 2 vehicles ahead of me; rescheduling for the lifter issue. I'll update as necessary.

Just got an update: apparently a seat bolt is stuck/stripped so they'll be rescheduling for all of it.

MODS: I figured I just keep posting in this thread for continuity of this issue but I will create my own if you think it's best. Just let me know if you'd like me to create my own.

**update: My service Manager says it's the lifters so my lady will be going under the knife sometime in the next week or so. I hate to do it but I hate the loud ticking worse...

Could I consider this a boob job? That just sounds better!

Thank you for letting us know! Hmm...my car sounds like that...pitty I`m overseas:(

This could be considered a boob job only if you put in a bigger cam. Do you work in the medical sector?

You're welcome and I'm a jack of all trades, master of none. If I had the money to upgrade the engine I would do that in a heartbeat!

My car is a LADY so the BOOB JOB just sounds better than ripping her apart. Maybe a BOOB Lift?!

When I took my car in I gave the service advisor the TSB#, just wanted everyone to know that part.

Took her in this morning for the warranty work

It felt about the same as taking one of my kid's in to have surgery.

At any rate, wish me luck!

Called my SA today after 4pm to check on the status( I was also getting the drivers seat cover replaced). He said he'd call me tomorrow and let me know what's going on with it. I'm not positive they're replacing the lifters yet to be honest. I'll probably just make a trip to the dealership tomorrow to get a straight answer.
