Exhaust Leak?

[BLoch]

I have an 05 KC SE. I've only had for 2 months and have 1800 miles on it. I have noticed over the last few days what sounds like an an exhaust leak coming from engine compartment on the drivers side. Has anyone here had problems with the exhaust manifold leaking and/or warping. I did a search and didn't find anything that helped.

No problems that I have ever heard of!

Shounds like you have the Tick. Mine sounds like it is coming from the Passenger side. If you search for "tick" you will find a lot of info on it.

New to forum, hello everyone.
Finally took my 04 LE 4x4 stock with 72K miles in yesterday after hearing the awful sound for about a year. Yes, a year. It's very inconvenient to keep leaving the truck with them and since the sound decreased significantly after about 5 min. of run and the general power was there and the gas mileage did not change I figured I could put it off. Anyway, they reported I have a "manifold leak". It is a warranty repair. I'm assuming it's an 'exhaust' manifold leak after reading these posts.
Symptoms:
When cold or even after a short off time (park, run into store etc.) start truck and not notice any unusual sound at idle or even revving while in park. As soon as I accelerate away the sound is VERY evident. Sounds like it's running on 5 cylinders and the exhaust is 'packed' with a clickety clack and a banana stuck up the tail pipe. Hard to describe but awful sound. The acceleration is way off too. But hammer it with full throttle and break thru it and I can feel the old nice power kick in quickly. Release throttle and accelerate again and the sound is still there but less and also it provides proper power quicker than when I first started. So at least for mine the quote I heard above 'as it heats the leak seals' seems true. After about 5 minutes the accel and sound are pretty much normal although I can still sense (hear) it's not quite right.

History of my Titan problems:
Bed liner bubble, they fixed free with a full replacement of LineX
Brakes, brakes, brakes! 3 times fixed 3 times failed, I replaced them with $1500 of stillen.com brakes
and they still pulse somewhat under hard braking but head and shoulders above anything stock.
Squeaks rattles, everything from the dash to the door panels (after they did the required TSB wire mod). After 2 tries they finally cured the dash squeaks with probably 5 lbs. felt, who knows, glad it's gone.

I've got a love/hate relationship with this truck. I love the get-up-and-go it has and the way it drives. BTW, I've test drove most of the domestic equivalents (GM-Dodge etc.) that have higher power specs and none of them can punch it up like my ole 72K Titan. Have not tried the new Tundra. I'm spoiled by that Titan power!
I hate that Nissan did not step up to the plate and provide a properly engineered front brake replacement package. F__K them. Because of that I will never buy Nissan again and will do my best to discourage anyone else from doing so. Cheesy plastic knobs (on mine anyway)

Please excuse the rant and the looong post, I had to vent a little. I'd like to add a thanks for all the great info I'm finding here, I wish I'd found this site a long time ago.

^^^^I've had a few problems with my T, but not enough to say I'd never buy another. In fact, I'm looking forward to the dropping prices so that I can some day buy a used one!

That sounds like what my truck has been doing for about a month now, I took it to the dealer but of coarse it was hot and they could not get the sound to replicate, I think because they were reving it in park instead of driving it, so they want me to leave it overnight whenever I get around to having enough time to let it.

Case closed for now... I just picked up truck and it sounds like it's old self, whew! Description says 'Manifold is cracked and causing leak'. Service receipt states they replaced 'Gasket-Exhaust' FP# 14036-7S001
and 'Manifold Exhaust' FP# 14002-7S00A. Cost $0.00 Maybe my faith in Nissan is a little better but I'll remain skeptical.

Edit- I was referring to this post (I have to put the dashes in the www part to post) w-w-w.titantalk.com/forums/titan-problems-dealer-service/69334-ticking-sound-sounds-like-exhasut-leak

Cracked exhaust manifolds on these engines is pretty common in my area. I probably replace 1-2 every couple months.

TitanTech659, Is there any trend you think could be found here? That is to say,
Are they older models like mine (1rst-2nd year production)? Maybe drivers who could be more aggressive like me? I'm not talking burning rubber but when it's time to move I move. Weather related? Just curious...
About being negative towards Nissan, I may have been very lucky with past vehicles but I can say that I have never had a vehicle needing so much work before. Especially considering that it is barely past only 4 years old!

[TitanTech659]

Well I can say that I haven't done many on 07's and none on 08's yet so I'm not really sure. The ones I have replaced usually look a little more "worn" in than others but here in Nebraska everyone's truck is usually used as a truck and not just a cruiser. Most Titans around here are owned by either farmers or construction workers.

Looks like there are a couple of these threads going.

Is this a warranty replacement job? I'm at 26K miles, so just out of the factory warranty but I do have a 5 year extended warranty that I need to get into my name (which is a pain-in-the-***, 4-6 week process).

[TitanTech659]

They are a warranty item.
