exhaust manifold

manifold on my 2.5 is leaking pretty bad gonna replace it within the next week or so, should i just get a replacement manifold or would it be worth it to get a header of some sort?

Shortly after posting this I called my buddy at my local jeep dealer, he tells me that jeep doesn't use an exhaust gasket? Hm..guess that would mean the manifold has to be cracked...or warped Idk...

Hmm. I guess I learned something. I never looked, but figured intake and exhaust gaskets would be separate. However, lots of vehicles (I guess not Jeep) come from the factory without exhaust manifold gaskets.

I have a 99 TJ 2.5 and had a combination of leaks on the exhaust. The manifold was cracked and had no manifold gasket. It's really not hard to change and if you have a wire welder (mig welder) you can weld up the crack in the manifold.

Well I replaced the manifold, there was not an exhaust gasket but there was an intake gasket, it was fairly simple just time consuming, especially cuz the stud closest to the firewall was busted off in the block lol what a pain...drilled it out replaced it with a grade 8 bolt :-) sounds great now!

Regarding the exhaust manifold, I have a 01 TJ and my exhaust manifold gasket appears to be leaking. It has been getting louder and louder each week. The intake/exhaust manifold gasket, will it just slip in if you trim the corners and clean the old surface plate after backing the exhaust and intake back? I plan on replacing it next weekend and was wondering what I was looking forward to.
Also does anyone know if there is a easy way to check the clutch without backing the transmission off or waiting for it to go out, I didn't see a inspection hole?

You have to take the air cleaner off, move the power steering pump since its bolted to the intake manifold, take the fuel rail off, then the intake manifold, there are various wires to unplug and a few vacuum tubes, I would take a picture while everything is plugged in just Incase... oh and ill tell you this just cuz I almost broke them, there are two little brackets on the bottom of the intake you have to take off too ...took me like 5 hours goes back together pretty fast though Lmk if you need anything else!
