6.0 Exhaust Leak

[mtpolarbear]

I did a complete EGR delete, new oil cooler and a new 5" Turbo Back exhaust recently. I seem to have an exhaust leak on the drivers side where the manifold hooks up to "Y" pipe. Any suggestions on how to fix? Do I need to take the turbo and "Y" pipe loose to fix? Is there a gasket I may have missed putting in? I need some help here, the fumes are killing me. Thanks guys!

The exhasut manifolds hook up to the "up-pipes", then the up-pipes connect to the y-pipe, then turbo.

Look at this link.
AP EXHAUST Part # 8693

More help please.

Where is it exactly leaking is the question.....If its the piece of pipe that bolts directly to the manifold where it is leaking its a ball and socket and you should be able to try to tighten them down more.

I did my EGR delete then shortly after I cracked a bellow in the up pipe after a month. If its leaking at a flange where bolts are you might be lucky and try tightening down or putting a gasket in.....But usually the bellow cracks and you have to take the turbo out again and replace the up pipe piece.

There are ways to check where it is leaking. On a cold fire I used my hand to follow the pipe up and find air hitting my hand. You have a good 30 second window to do this so have a freind fire up the truck and try that. Or a automotive stethescope works also.

Also on your exhaust make sure you downpipe has at least a finger space away from the up pipes. My bud just did a 4 inch downpipe and we had to beat it in because he just bolted it on and when the truck shook it rubbed the up pipe cracking it.

That is some great useful info! I'll start looking! Thanks Rotbody!

The link I gave you is to seal the connection between the manifold and up-pipe. You ma have a crack like stated by rotbody.

That's what I thought but wasn't sure. Thanks for clearing that up! I'm tearing in to it tomorrow so I'll post what I find.
