Exhaust Leak? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hello everyone, so I noticed a major ticking sound coming from the left side exhaust header. I took some videos and I've narrowed it down to a possible valve adjustment needed or an exhaust Leak. I also noticed a bolt missing from the rear of the exhaust header.

I posted these videos on Vimeo so don't worry the links are legit lol..

I think you answered your question.....if a header bolt is missing.

Ed805ls3 · 06-13-2017, 06:36 AM

But here's the thing. The exhaust header bolt has been missing for some time and all of a sudden a few weeks ago it started to sound the way it does.

Im sure that area is going to be weak. Eventually its going to blow by the gasket. Order up a new factory gasket and bolt.....get that fixed.

Replacing missing bolt, and gasket if damaged - then report back! Those header flanges can be pretty stout and hold even without the bolt for a while, but eventually they'll start leaking.

Thanks guys I appreciate it and I'll try to get it fixed.

So I took the headers off the bolt is stripped... so leaves me in a pickle on what the next should be... any recommendations?

Which one is it? Some of these you could maybe get onto with a pair of needle nose vice grips cranked up nice and tight. Some times you can take a dremel and cut the head into a square to get a better bite on.

Avenging Orange · 06-15-2017, 10:45 PM

If you can get to it....you can (as we called it back in the day) helicoil.

It's located at the rear of the passengers side.. it's the hardest one to get too. I was thinking of welding a nut on the end and trying to remove it with a socket wrench that way...what you think? Your idea isn't bad either but the location might make it hard.

What's helicoil It?! Never heard that term before I'm out to google that lol...

avido · 06-16-2017, 02:35 AM

connect a scanner and check your long term fuel trim. since the leak is before you will see a difference between the banks. it could be one of them adding fuen and one removing.

a elicoil is just a new thread . you have to drill a bigger hole, and then using the elicoil you can get a new thread. since the position is ungodly you should have the job done by a professional

Avenging Orange · 06-16-2017, 07:25 AM

Ahhh, so the bolt broke off. When you said stripped I thought you meant the bolt was gone and threads were stripped.
Helicoil is a way to replace the threads. Drill it, tap it and recoil.
Good luck.
