I always wondered what that metronome noise was...lol. I thought it was the serpentine belt making a noise at the same spot every rotation. Now I know!

GM has a TSB out for this concern, its a cover that goes over the direct injection pump to isolate the noise.

Hmmm, yeah could someone with some info post the TSB? Pics/info on the cover? As long as the ticking isn't a sign of some other problem, it doesn't bother me at all :shrug: That being said, I'd probably get it serviced by the dealer whenever I happen to take it in (maybe for the stage kit) if the TSB thing is true.

Hey guys I've just read over this thread but I wanna ask anyways.
I'm looking into buying a used 2008 TC and when I popped the hood with the engine running there was a constant pinging noise, almost like pennies inside the engine. Is this the direct injection noise that you're all talking about? When you're inside the car idling of driving you can't hear it at all thou.

I was listening to my engine tonight, and this new noise coming from it. I know of the common DI tick, but this sounds like someone is slapping a bambo stick on flesh. here is the youtube link

That bambo stick on flesh sound is normal. You should hear the engine during a cold start. It sounds like it is going to blow up. I wish our 4-bangers sounded more like superbike engines....

Diesel is a funny comparison... I've literally had someone ask me "since when has GM put diesels in cars?"

Thanks for all this information. I just recently purchased a 08 SS and I noticed this ticking sound too. It had me worried, but I went to this form and, like I always do, got great information about what I was noticing. Now I know that this is a normal sound! Thank you all again!

Yep, there's the ticking from the OHC valvetrain, the slower ticking from the direct injection system, and the "person in the trunk kicking" sound from the evaporative emissions system.

Often times... when the car is stationary... I can hear is knocking noise coming from either under or rear of the car... happens every 20-25 secs for a little while...
is that the evaporative emissions system?

Yeah that's a normal noise too. It will scare you sometimes even though you know it is normal. You can usually only hear that one at a complete stop, but it's loud if you don't have the stereo on which would mask the kicking or knocking sound coming from behind you.

Yup thats the canister purge solenoid on the canister clunking. It happens about 10 or 15 minutes after you take off and you usually hear it 3 or 4 times. The ECM runs a diagnostic on the fuel tank to insure it has no air leaks so it fills and vents the tank. It does it everytime you start the car and run it for the specified time. Yes it sounds like someone is kicking the spare tire well in the trunk from underneath.
I just tell everyone I got one of the Poteet brothers (Bad Boyz 2) in the trunk.
