I put in lt's along with an ory this past thursday and everythings been great so far headers already had 500 mi on them when i put them in. Today I noticed a tick coming from the headers, it sounds like the drivers side more... I rechecked all the bolts and everything was tight new mls gaskets were used in the install and using a stethescope i checked all the primaries and clamps... I found nothing out of the ordinary. Below is a video, could this just be the normal header tick? http://www.youtube.com/watch?v=GrNfAOiP85E

 

Hmm that doesnt sound like header tick to me.... Did it make the ticking sound when you first put them on?

 

i honestly dont remember just went out and triple checked the heads and theyre tight same with the collectors. also i should add that unlike an exhast leak this is quiet when cold and becomes sslightly more noticeable when warm

 

also noise is aduible mainly below the car up top i hear nothing. no egr or air either.

 

someone else had this same problem and it turned out there bolt was too long and it was bottoming out. so the headers werent tight causing it to tick...

 

theyre sstock bolts and the flanges were the same thickness as the manifolds

 

I just drove it 200 miles back up to school last nt and the tick is no worse and i got no codes when im back home for xmas ill investigate further but is it going to hurt any of the sensors running it?

 

sounds like valvetrain noise to me man... I would pull tappet covers and take a look at it the next chance you get. See if you can narrow it down to which side its coming from
