Exhaust leak on truck?

2007 Nissan Titan w/120k. Sounds like it may have developed an exhaust leak. Any common spots to check or recommendations on how best to track it down? And Broome...I don't want to buy a new truck just yet.

 

Heard the manifolds Crack on the titans....

 

Thanks for the info...will take a look.
I've had this truck since new and have had zero problems with it so far, so hopefully this doesn't turn out to be too much of a pain in the ass.

 

If you live where it's cold, you can just start the truck up and look for the steam/water vapor exiting the crack/hole/whatever. The hole on the end of your exhaust system doesn't count!

 

This. It wasn't specifically described to me as being a Titan problem but it came up several times (even from Nissan salesmen) when discussing the Armada SUV (which is based on the Titan). They said it happens on pretty much all of them and is pretty expensive to fix (in their shop, I'm sure there's a relatively inexpensive way to do it if you're mechanically competent).

 

Not only the manifolds...check where the pipe actually comes out of the exhaust (near your rear axle). I thought I had an exhaust leak and I did; the entire rear pipe had rotted apart and fallen off!

 

Exhaust hangers have a habit of breaking on titans, it really can fuck up a good part of the exhaust. Good chance it's probably the manifolds though.

Replace your rear shackles if you're still on the originals. Scary how many people have had them snap and a leaf spring punch through the bed.

 

I live in Florida, so looking for vapor would be harder to do. Will be taking a look at all of the issues you've mentioned so far. A quick Google search does turn up the manifold issue that Nissan was covering for 8 years/ 80,000 miles, but it's not a true recall so I am screwed there.

 

I would probably look where all the noise is coming from.....just sayin....

 

Never thought of that

 

Does the noise get quieter after the engine warms up? If so, that's a exhaust manifold leak or a donut gasket.

 

Check the manifold/head bolts, too.

 

Noise at idle gets quieter but if I get into the gas after warm I still hear it.

 

Done with work for the day, so I will report back soon with my findings.

 

Have someone put their hand over the end of the tail pipe with it running, the pressure will build and the leak should become very apparent. You may even find some leaks that aren't even noticeable at any other time. Ticking when the engine is cold is normally a sign of something really close to the engine leaking.

 

Noise is definitely coming from the front passenger side near the manifold. Can't see it to visually inspect for cracks, etc due to the heat shield that is on it. Guess I am going to have to dig a little deeper. Thanks for the suggestions.

 

manifolds are notorious for it on that truck, buddy has had to fix both sides of his.. throw on some headers like he did

 

Seemed plenty tight.

 

Probably why I will end up doing if I can verify that the manifolds are indeed the problem.
