O2 sensors going bad?
O2 sensors going bad? I recently had some headers installed with o2 extensions. Since then, I have noticed a "clicking" noise that seems to be coming from the headers or from the back side of the engine, not quite sure. Are the o2 sensors located on the headers? And can this clicking noise be due to my o2's failing? thanks
"......o2 sensors located on the headers? " YEP
"....can this clicking noise be due to my o2's failing? " Do not think so
I think clicking would be a exhoust leak between head and header flang.
could be header bumping frame/body, but do not think so

ps check the header bolts<<<

Thanks for the reply, I can check if the header bolts were tightened properly. Hope that solves the problem. An exhaust leak can cause a clicking noise? The header was welded on to the y-pipe so it's possible that it wasn't welded completely.
"..An exhaust leak can cause a clicking noise?..." yep
".. The header was welded on to the y-pipe so it's possible that it wasn't welded completely." do not think so ... ticking/clicking come from flange to head being loose or warped flange

1 7/8" headers often cause a clicking.....or ticking sound. Is just the nature of the header and the tapping of the valve train sending that tick noise down through them.
When I got my 427ci installed and my 1 7/8" headers.....same complaint I had to my builder/installer. He said that's what it was and that in time I won't even notice it anymore.....he was right. The only time I hear it now it when I drive along side and close to curb and that ticking noise bounces off the curb and makes it more apparent. Then when I'm clear of the curb its gone.....
If you have no leaks that's probably what it is.
And no.....02 sensors make zero noise. You may get codes soon because headers get a lot hotter than stock exhaust.......you will have to get Denso 02 sensors....they handle that heat better than the old AC Delco sensors and better than the Bosch.

I took another look today, all the bolts for the headers are good and I didn't notice any part of it hitting the body. I think it's just what ls6427 said, sounds like my valvetrain is more audible. Guess i'll get used to it, thanks.

With your driver window down, with your foot still on the gas holding steady rpm, the next time you drive close to a raised curb.....it will get louder from the sound bouncing off it, then it will go away when the curb goes away.
Also, maybe check for a broken spring(s).....that makes that valve train tick a lot more noticeable.
