How cute is this....

While I love the smell of burning fuel.... I don't want to fall asleep at the wheel because of it... any suggestions on a replacement? How difficult is it to replace? I don't have a garage and an wondering If I could do it in my apartment parking lot in a day.

If you can get all of the bolts out without breaking them. Then I would think its possible to do in a weekend. Kinda tough to do it in just a day.

You need to take the intake manifold off to get the exhaust header out. And that alone will take you the better part of the day to dismantle. I know there will be some of those "all-pro" mechanics that are going to say..."just a few hours"...trust me, I work on these things almost everyday. If you are by yourself and all the bolts come out without any trouble (rarely), then I would say an 8hr day to tear it all apart, and another to put it all back together.

But, always expect the unexpected. Snapped off bolts need to be drilled out and re-tapped.

You could possible get some JB Weld, and pack it in there to get you by til you can work on it. I have done that before. It wont last long because of the header heat. But it will last a few weeks.

Yep! Where the head goes from 4 to 2 it's got a pretty big gap... I was thinking about getting it welded BUT the crack is in such a stupid place that I'd have to take the header off anyways to have that done... might as well replace it right?

I'm hardly all pro but I was able to strip and remove my 4 banger in a weekend. This is much simpler. You should be able to have the exhaust off in less than a day. It should be a weekend job to replace the header.

This is assuming you don't run into any jammed bolts. I was fortunate in my case and didn't have a single bolt give me a problem.

I had a cracked exhaust manifold on my PU truck that I was able to repair with some stuff called "Bluemagic", "xtreme QuickSteel". High temperature metal repair, good to 2400 degrees F. I used a wire brush wheel on the Dremel and cleaned the crack up, smeared the stuff on it and left it alone until the next day. It has held together fine, I didn't intend it to be a permanent repair but it seems to be holding fine. Just a suggestion.

Don't weld it or bandaid it, just replace it. Its not too bad of a job, if you're ambitious (and don't drink too many beers in the process) you can get it done in a day, and get a new header off amazon or eBay for around $100-150 dollars. I just did mine, I found an eBay auction that started low and I was the only bidder, got the new ss header for $95

There's a write up on how to do it on here somewhere. I'd post a link but um on my phone.

Replace it. I did mine back in January and I'm thankful that I did. Get all the materials first, that way you don't have unnecessary delays. Get o-rings for the injectors. Throttle body gasket, exhaust manifold gasket, exhaust manifold hardware kit.

I used this write up when I did mine: http://www.jeepforum.com/forum/f12/h...ifold-1063245/
