Cracked/Broken Exhaust Manifold
 
After my install of the 3 inch zone lift, while I drove it up onto the alignment machine, 2 trustworthy mechanics told me just by listening to my jeep drive the exhaust manifold was cracked, once lifted up we crawled under it and sure enough, it is. My question is how much should I be paying for one of these? Which kind or brand does everyone prefer? How difficult is the removal and install, and are there any tricks to it? Sorry, lots of questions, im not too knowledgable of exhausts, and thanks in advance for anyone willing to help out!!!

Buy one off eBay or I got mine from 1AAUTO a few years ago because shipping to Hawaii was cheaper. My kid just replaced his last month and I think he got his off Amazon. Should be anywhere from $90-$120 for one depending on where you buy it. I used a writeup from Daily Driven TJ and it took me about 4 hours taking my time. Heres a link. http://www.dailydriventj.com/forum/viewtopic.php?t=847

I foumd one on ebay new for 80 bucks free shippimg, this was where the shop recommended I look bexause the ends of it are like rubber or somethimg so they can flex and not break like the stock one. Only thing I was concerned about was it was for a cj, yj, and tj... like I said im not too knowledgable on exhaust but do all three models have the same exhaust manifold? Ill try to post up a link for you and anyone else to get a better idea of the one I found, and thanks for that writeup, will definately be usimg that.

Will that one work?

thgr8alex 04-03-2013 11:17 PM

And is that of decent quality?

Just by looking at the picture I'm not sure that would be the right one...

I just put this one on my 97 tj about 2 weeks ago, wasn't to hard to do, you should do it yourself if you can.

Exhaust manifolds are easy to install yourself if you've got a decent wrench set. They're only like 10-12 bolts. I've found some manifolds for $60-80 at Napa and AdvancedAutoParts.

Just curious if they told you what they heard? Ive got an intermittent hiss that i think is some kind of leak.

That sounds more like an intake manifold, does it get louder when you accelerate? An exhaust manifold is just loud as heck when your idling.

I just replaced my cracked exhaust manifold with a header and a week later replaced my cracked intake manifold. Jeep is much quieter now.

Check engine light popped on afterwards and showed #6 misfire. popped again, reset and tightened up the bolts ran a week no light. Pulled to replace gasket and discovered the crack in the intake manifold.

thgr8alex 04-04-2013 07:20 AM

I definately will be doing it myself so thats good to hear its an easy install. 10 or 12 bolts. Idk exactly what they heard, just said it was louder than it should be and air is getting inside when I let off gas and could be a big problem if im in a creek or something. He asked if I heard a lot of engine noise in the cab, I do and I said yes and he said yep, exhaust manifold. And it should be quiter after I put a new one in

Thanks jerry for that link, im gonna crawl under it today to get a more detailed idea of what I should order. Anyome else have any links or brands of one they got? Or are they all basically the same, just different prices? Thanks for all the help so far

Nah. Doesnt get louder. I can only really hear it when i pull up next to another car and the sound reflects. Sounds like morse code. And my tach dips ever so slightly in time with it.

Sorry to hijack the thread :-\

No worries man! New information never hurts.. I just need to get on this exhaust manifold relatively soon, I jut need to do a bit more research and get the right thing. Worst thing ever is when you order a part, wait all week, get so excited when it arrives only to find out its the wrong part...

thgr8alex 06-12-2013 12:50 PM

Ok so im finally getting around to doing my exhaust manifold. Was thinking of buying a new one and doing myself but really not interested after i read a few write ups haha. At my local exhaust shop they said they could pull the manifold off and repair it and put a new gasket on in one day for 240. Is this a good deal? Will the repair hold up?
