No, its def not that man. I know cars pretty well, and ive worked on everyone ive ever owned, and ive never heard this before. It sounds like a marble dropping in a cup after i shut the car down and its everytime too...
Crazy stuff, and its bugging the hell outta me

 

i know exactly wat ya mean, an my car does the exact same thing.... it has ever since i can remember an i got mine new... meh... my car makes tons of noises, most of which i drown out now anyways lol

 

Mine makes a clicking sound for about 1 to 1.5 seconds after initial motor firing, only during cold start-ups. Sounds more destructive than direct injection...

 

As for the car "ticking" after you turn it off, it's the metal cooling off and expanding from the turbo/exhaust. Somebody obviously dropped out of school...

 

that's totally the high pressure fuel pump.

it's noisy enough that 2008 & early 2009 CSS's had a recall to install an insulating cover ~ to quiet it down some...

 

I get the exact same sound. I kind of feel like I hear it once I get out of the car. Not exactly right after I shut it off. I almost feel like it has something to do with the car balancing out when I get my fat ass out of the car(240lbs).

 

Glad you made this a sticky, so easy to find lol i just bought a 2010 SS and that clicking was my only concern so far about the car

 

Hey guys mine does the same thing but i also have a lifter bad too but diff sound!. but I do have to ask I have alot of carbon on tale pipe and the plugs r black and the tipe is white. any help would be great.

mods are dejon inner finder cai and inner cooler kit all piping and some kinda cat back all this was on the car when i bout it.

 

the sound aaron is referring to is common with cam driven pump when car shuts off i have yet to research the technical term or explaination i have the service manual on order upon finding out shall report back. now in regards to valvetrain these cars im noticing that these cars are very noisey and that people tend to point fingers at the fuel system, from my guesses we tend to over rev the cars and damage the valvetrains, the cars cam phasing abilities then start to manipulate timing to compensate for weakening valve components eventually resulting in drastic driveability issues or the car looping like it has a cam. now i imagine everyone on here never over revs there cars and are perfect drivers. im just not that guy...lol

my two cents

 

ticking could be the lash adjusters too when they are bad

 

yup, i have all of these noises too, not concerned at all though.

just thought this would be a good thing to post on this sticky

 

The loud clicking noise is the fuel injector. The fuel pump is high pressurize and since the cobalt tc are direct injection and really doesnt need high pressure. GM said this is a normal condition and to dont replace anything just for that noise

 

Yeah, everyone i've ever heard ( including mine ) does that! i thought it was a problem at first and was flipping out, but its the direct injection just ticking, it does away after a while of running it tho.

 

good to know, i forwarded this thread to the guys on the regal forum... no one had a clue what it was.

 

Wait until you have direct injection clicking with 6 puck clutch chatter.

 

i have a zzp stage 4+ and aluminum flywheel, my car at idle is noisy to say the least.

 

Haha I know exactly what you're talking about.

 

ohhhhh!!!!! nevermind!!!

 

Hey guys I'm new to the forum I was reading all the comments about normal tick sounds and wanted your blessing lol this sound good or need a new timing chain tensioner? Gonna pick it up Monday if it seems normal to you guys 1 owner but engine bay filthy... https://youtu.be/_JQxGfy0Zf4

 

Sounds like a normal lnf cold start to me. Let it warm up a bit and go into closed loop. The sound will sort of calm down a bit and turn into an "oscillating" clicking at idle, in 1 or so second increments.

 

They are fairly noisy on start up every one I have ever heard is like that for some reason

 

Thanks for taking a listen it sounds that way even after warming up so im almost afraid it needs new guides and tensioner or more its gone 89k miles and he says he never had the noise looked at not sure when it started this noisey.. he wants 9500 for the car pass safety and emissions no check engine light.. safe or pass would you guys say? He says he never drove it over 90 mph he pretty old

 

Well even so at 89k it would be best to change those parts anyway or by 100k.

 

Defiantly sounds like good advise it failed emissions with p0013 told him how to fix it using forum inst for exhaust solenoid but he's taking it to the stealership asked him to ask about the timing chain tensioner hopefully he does that utube clip I captured from the car is freaking me out.. could it be like a broken rocker or vavlve spring or would it be even more gnarly sounding? Thx
