Today on my way back from lunch my cobalt started making a werid crackling noise coming from where the headers are.the sound wont go away. Any ideas on what the problem might be?????????????

 

stock or aftermarker headers....If after market maybe the bolts just need to be a little tighter???

 

Stock

 

crackling sound or a ticking noise like the timing chain slapping around because the tensioner has worn out?

is the sound coming from the passenger side/rear of the motor?

 

it does sound like a ticking sound and it sound like its comming from the driver side it might be the passenger side i will have to check again

 

Going to my dealership tomorrow to see what the problem hopefully nothing major and can get fixed in a couple of hours

 

bad gasket?

 

does it go away when you are driving at 2500 or so and up rpm? then come back when you're idling or really low rpm?

if so you can pretty much bet it's the timing chain tensioner. that's a $20~ part from napa and takes about 10 minutes to install a new one

 

i took my baby to the shop today it was the flex pipe its freak in broken but thank god for warranty. it goes in the shop for a new one on Tuesday yay!!!

 

good deal then, free fixes are the best
