Swoosh noise headers
 

So i installed my headerback exhaust around 12 days ago. Install took a while but thats just because of inexperience. Anyway there was one bolt that I had trouble reaching so I hand tightened it as much as i could and i couldn't fit my wrench or ratchet so i found some tiny vice grips and tried to tighten it further with that. No leaks everything was fine.

But now im starting to hear swoosh noises as if air was escaping. I've read that its normal for the tomei uel headers to make this noise because of the thinner metal used, but im so paranoid.

So, whenever im free im going to attempt to tighten everything again, but im wondering if you guys have any tips or suggestions on reaching that one bolt?

As they heat cycle you usually need to retighten them a couple times.

Will do!

Don't use vice grips :slap:

Get a socket extension get back up there and do it right. Torque those bolts where the header bolts into the block. Do it in the right pattern too (look for a YT video on how to do this). You WILL have CELs and all sorts of issues if you get it wrong.

I used a universal and a wobble extension to get to that nut. a crows foot would be better, but I didn't have one.

Yep. When I installed headers I heat cycled the engine a few times while everything was apart before doing final torque checks.

This.

I love me some wobble extensions!

Yes boss ...... yes boss .......right away boss .........:bonk:


:D

Make sure the flange nuts at the exhaust ports are properly torqued... but that's not the problem. Exhaust leaks at the ports make a popping sound.

I've only heard the whoosh in 2 situations, The first was when the flange nuts between my mid and rear pipe fell out. The other is the normal sound that every thin-walled header makes.

So, @Ultramaroon , I reckon you wouldn't think much of my tool box ....... :sigh:

Are you saying you can get ahold of that bolt with a pair of vice grips but can't get one of these on it .........??

I ......:iono:

What "one bolt" are we talking about? All the bolts to the block are super easy to reach with just a ratchet with extension. The bolts I have a hard time with are the ones on both ends of of the over pipe. I would love to get a torque wrench on them but there isn't enough clearance. I hate torquing on swivels because it throws off the spec. At least with a crowfoot you can do the math to get the correct torque spec on the bolt. I need to get a some crowfoots for my tool box.

Yea excuse me noob habits lol, I have an extension I think I’m going to go buy some of those flexible joints bcuz it’s at a really weird angle

Passengers side it’s between the Tomei pipes so it’s at a really weird angle. I just bought a torque wrench and some of those flexible joints. Hopefully I can reach it.

Can anyone direct me to a thread that has the proper spec I should torque all the exhaust bolts and nuts to?
