With the Armada being 4 years old How many miles do you have on your Mada"? I just turned 90,000 on my 04 SE.
Mine leak but are only detectable under acceleration against a wall with the windows down.....How are so many of you high milers getting so far down the road without having to do the exhaust manifolds?
Who says we haven't replaced the exhaust manifold/cats? Just recently, I recently had my fourth pair installed. Have had various results with aftermarket cats. I got about 150K out of the factory installed manifolds.How are so many of you high milers getting so far down the road without having to do the exhaust manifolds?
Holy cow thats alot of miles! What manifolds are you running now, and have you considered Cajun B-Pipes JBA vband catted headers?Well, I finally hit the next milestone. My 2005 Armada currently shows 601,622 miles. Yeah, there have been some hurdles along the way with this many miles. Heck, I even had to have the driver door hinges replaced because they just plain wore out. I say "pfft" to all of you with your synthetic fluids. This baby gets conventional oil every three thousand faithfully and I have every receipt for those 200 oil changes. I even got through Buffalo a couple weeks ago after they got those two lake effect blizzards. Man, they get some snow up there!
Not running anything special; whatever aftermarket version my mechanic wants to use. But definitely not a Nissan part. I think he said they are Wagner (?). Not 100% sure. This is my daily, so I keep it mostly stock. Only change has been the stainless from the manifolds back. I live in Pennsylvania, so I need to get through emission testing. Not sure if your alternatives would work. I keep the crazy mods for my 1990 Nissan Hardbody convertible. The weird thing is that old truck only has 19K miles on it. You can still see the chalk of the frame from the factory.Holy cow thats alot of miles! What manifolds are you running now, and have you considered Cajun B-Pipes JBA vband catted headers?
Yeah I totally understand wanting to keep it stock for your daily. But just for future reference, Cajuns headers are CARB compliant and direct bolt on, the only headache is that a tune is recommended, but they have streamlined that process for the most part. Also, what have you paid in labor to replace the manifolds, I have heard it can be upwards of $1000.Not running anything special; whatever aftermarket version my mechanic wants to use.

I also used conventional oil in my 05 Pathfinder every 4K miles faithfully and I put 248K miles on the odometer.This baby gets conventional oil every three thousand faithfully
Honestly, for labor and parts for replacing both mainfolds and o2 sensors, I shelled out well over $1000. I appreciate your feedback and will circle back if this pair go bad. I went with a pair from Jegs on the third replacement and those were junk (lasted under 60K miles), so I went back to a more traditional supplier. I have been getting well over !20K miles on this brand so that would be after 720K miles on the old girl. I don't think I will get that far unfortunately.Yeah I totally understand wanting to keep it stock for your daily.

Good to know, mine need to be replaced, so I will need to decide on a pair soon or attempt to weld them. Ive heard that some dealers refuse to do manifolds on these vehicles, but that just seems bizarre to me.Honestly, for labor and parts for replacing both mainfolds and o2 sensors, I shelled out well over $1000.

Maybe you misunderstood my problems. I replaced the manifolds because the cats failed to pass the emission tests. When you drive as many miles as I do, the cats simply wear out from lack of the reactive metals. I did not have any issues with breakage. I did have one mechanic who refused to do it when the second pair went bad. Yes, he described it as a "big" job.Good to know, mine need to be replaced, so I will need to decide on a pair soon or attempt to weld them.

I see, my manifolds are cracked and are making a ticking sound. Not passing emissions because of failed cats is something I haven't seen much here, but then again, neither is a 600k mile armadaMaybe you misunderstood my problems.
