Manifold finally cracked. Long term problems?

Was just wondering if driving it around a while will be a big problem? If so, what are the problems I'm facing by doing this? Happened a few weeks ago and now it's getting louder and louder. Don't know if it's in my head, but it seems like I've lost a lot of power. Doesn't get up and go like she used to! Any thoughts?(except obviously replacing it! Just don't have the cash now!)

Many muffle shops can weld these areas for 30 bucks - that is, of course, the crack is at a place reachable to them without removing the piece. Make a few calls to the local shops. they may surprise you with how cheaply you can get away with it for a while.

As to your original inquiry, I do not know for sure what long term problems you will encounter.

I felt a loss of power when mine cracked. I don't think there's any major effects, except power and mpg. How many miles are on the jeep? I've seen a few threads on here that people got the manifold replaced through jeep under warranty. Try doing a search in here for cracked manifold.

cracked manifold will get you a lot of posts!!! It's all too common. I think I drove mine that way for about a couple months and maybe it was in my head too, but I thought it seemed more powerful once I replaced it. My only advice is save up enough to get a Banks! Do a search on Manifold and you'll see a lot of people reccommending them. It was a pain, but I replaced it with some help from my father-in-law, and now that it's done I'm really glad that I didn't skimp and get a cheapie. I really don't want to have to do that again! Good Luck!!!

I replaced mine with a Borla header. I would have gone with the banks, but i needed it right away and they were on back order. I'll agree it's a pain to install but well worth it.

If you have the crack welded it will just break again.

mine was slightly cracked when i purchased my jeep at 68,000....it jsut made a slight rumble, sounded pretty nice on acceleration. then it cracked more at 78,000 7 months later and got obnoxiously loud. just when i thought it couldn't get worse one of the pipes completely split on the way to the badlands.....the thing sounded like a revved up corvette engine when it was just idleing. from what i've expereinced lose power and your gas mileage will drop majorly (i went from 17 to 10 along with a slow response when you hit the gas). from what i read you have a possibility of losing an O2 sensor or ruining your cat (i just read that on the forum during a search)....the check engine light will eventually come on because the O2 sensor is not getting the right readings mine also had a hard time ideling with teh completely cracked manifold...it would bog down and jump up which was most likely relaved to the O2 sensor not getting the correct readings

i purchased a replacement on ebay from megapartz. its $121 after shipping and comes with a free gasket kit. it has a lifetime warranty and fit right on without any problems. from what i read all the headers are prone to cracking (even banks and borla will crack) but with those you have to send in the cracked manifold before you get a new one.....which results in atleast 2 weeks of downtime for your jeep! megapartz states all you have to do is contact them if you have a problem and a new one is shipped out immediately.

Yeah, did a search and it came with about 500 results. I didn't see any titles relating to what I was looking for. I was wondering about the O2 mostly or doing any long term damage to my engine. It'll be a few more weeks before I can get the cash to replace it...

Someone asked about my mileage and warranty...Nope, I have about 105k and it's a '98. I can imagine the laughter I'd get if I even asked for it!

Thanks for the replies!
