Just got my Cobalt about two months ago and all of the sudden it makes a ticking noise on start up, but only lately in the colder weather. I've heard the LSJ guys say that their timing chain tensioners make this sound when they go, but I just wanted to get some ideas from the LAP guys to see if you could shed anymore light on this subject for me. The car just rolled over 36K and the sound only started recently when the weather got colder down here in FL. Any help is appreciated.

 

mine does the same thing... nothing out of the ordinary though... i may go to the dealer and make them fix it

 

I already took it to them and they said its normal on cold start ups. But now it's gone. WTF?

 

mine is kinda more or less on the colderside

 

Yea, they told me that its just the valves tapping until oil gets to them. I was like arent they not supposed to dry start? lol

 

mine is very "tapy?" untill about 135 degrees.... but mine also makes a horribly loud noise for like 2 sec every once in a while on cold starts.... its hard to discribe. lol but yes the ticking noise is normal when cold, thats what the dealer told me lol

 

WTH? I never had this problem with my SVT dammit! lol

 

lol. im just glad im covered from bumper to bumper till 100K lol

 

This is true, but bumper to bumper is only 32K I believe. The drivetrain warranty is 100K

 

the ecotec is a direct-injection motor and it is going to make that sound right up till about 140 degrees XD mine does the same thing but it’s a noise common to a direct-injection motor.

 

I hear it on mine on cold start-up's also.

 

Thanks guys for clearing this up! I'm glad my car isnt gonna explode or something.....yet.

 

yea, I bought a warranty lol. its through amarican warranty corp? lol it has been well worth it!

 

ohh my bad man, I was talking about my 2.4 lol I failed at seeing that your asking about a 2.2 lol

 

lol its all good man, everybodys input was needed. Just glad that my car isnt gonna be dead soon. haha

 

all it is is a little bit of valve chatter..no biggie

 

Thank you sir!

 

use mobile1 and put lucas oil synthetic in it. Not a noise and it was 35 this morning.

 

I've used Mobil1 full synthetic at the last oil change, which is when it started acting up. lol
