question's on 2.5 exhaust manifold

I think I have a leak in the manifold somewhere cosest to the block side of the header. Ive looked online and some sites say there is no gasket between manifold and block others say there is a all in one intake/exhaust. My question or questions are is there a gasket and is this a difficult job if there is a all in one. ive changed v8 headers but never tackled one where the intake sits ontop of the exhaust

TJ 2.5 Exhaust Manifold.

Hi There,

I just had mine changed. I too have read about there not being a gasket but my new manifold came with one. The install is pretty straight forward if you are comfortable removing the air intake, hoses etc. Just remember to spray the bolts with WD40 or similar the day before as they will be pretty tight on there.
I was going away for a couple of days so I got my local garage to change it for me while I was away but its not a tough job to do yourself.

I planned on PBing the exhaust bolts a few days in a row before the install. Im hoping that I don't have to take the intake off. I bought the manifold from Autozone ($114 ) . Supposed to come with all gaskets needed. I noticed the one on there now has no heatshield and the down pipe has bolts not studs so im guessing its been changed before. I have just over 106k on her now.

Well got it changed. I assisted but most of the work was done by a pro. It really wasnt that bad. Taking the fuel rail off was probably the most scary for me but its really not that tough. A little over 2 hours and basic hand tools. I learned that jeeps are real simple machines compared to most vehicles out there.

Sorry for the delay of my reply but I have been away. I was charged $150 for the labor.
