4cyl exhaust manifold replacement

I did a quick serach but did not see anything. Is there a write up on replacing the exhaust manifold? I am pulling a cracked stocker and bolting up a stock replacement.

Are there any hidden tricks or lurking potential problems?

Does the intake need to come off?

Thanks

Craig

I would leave as much attached to intake manifold as I could and just move it to the side in order to get exhaust manifold out also night before i would soak exhaust bolts and egr tube in pb blaster or something that will penetrate rust to free up any rusted bolts very common with exhaust parts.

Good deal...so basically typical job for the most part. I wish I could wait longer on mine but it is getting to be tank-like.

Thanks again. I'll let you know if I encounter anything 'funky'.

you're better off slapping on a header. I just did it on my I6. You have to remove the intake, powersteering pump, and all that good stuff. As soon as i find out why I have such a rough idle I will post pics

ferrachi...is your header a direct bolt on replacement...no need to change any of the exhaust?

Did you see or feel any noticeable gains in torque or power?

Thanks for the input.

when i did mine, i had to grind a little on the skirts. they wouldnt let the intake manifold sit in there all the way. once i figured that out, it was relatively easy

A quick search (jeep header 2.5) yields 2 hits. One is 225 (pacesetter) and the other 389 (Banks). A bit pricey.

dont waste your money. i think i paid a little over a hundred for my manifold. you're not going to see appreciable gains from the header on the 4 banger.

I agree...I am swapping out my broken manifold with a stock replacement.
