Any Tips on Installing an Exhaust Manifold?

Hey, I just bought a 97 TJ with the 4.0 and it has an exhaust leak at the header/manifold so I bought a new one off of ebay. Any tips before I jump in?

start hosing the manifold bolts with PB blaster every day for a week before you decide to do it.

Or buy some AeroKroil and you won't have to wait more than a minute or two for the nuts to come loose. I busted knuckles on old bolts for years until I bought some. Much better than anything else IMO. I can't figure out how to post a link but this is the website: (I don't work for Kano Labs by the way)

I like for it to shine even thought it is muddy most of the time!

1. You don't have to remove the fuel rail.
2. Make sure you have the special tool to release the fuel line.
3. Sometimes the ebay special gaskets don't align properly. Mine didn't, so I bought a Fel Pro.
4. Universals and extensions are your friend!
5. Upon installation, start by screwing in the bottom bolts loosely and mount the manifold on top of the bolts, making sure it sits flush. This is a job saver - rather than inserting the manifold and attempting to screw the bolts on afterward.
6. Did I mention, universals and extensions are your friend!
