I have heard of the '97 and up intake manifold swap to replace the more square intake of the earlier years. With all the mixed info on doing this, what is everyone's consensus on this?
Not worth it.

This pretty much explains my current project goings-on…

Quote: leave the injectors in the rail pull them out of the intake manifold, lay the entire thing over out of the way. and yes, both manifolds come off.
Or you could just leave the fuel rail and injectors on the intake manifold, disconnect it from the fuel line to remove it. That works just as well, right?

Yes. That's actually the FSM procedure. Of course, if Cruiser suggests the injector removal, then it's worthy advice. I'm looking at it like I can go with the injector removal OR the line disconnection. Whichever seems easier (or if I have trouble with my initial choice) will determine what I actually end up doing.

It might depend on how easy it is to disconnect the fuel line. Some time in the 90s they changed it to one of the disconnects where you need the special silly tool. I've never used one but they look easy

When I did mine, I pulled the rail complete with injectors still in it, fuel line still connected and then just flopped it over to the front of the Jeep. No gas spillage and no fancy tools needed.

yes, it does. there is more than one way to skin a cat. this is why most guys need to go work on stuff before regurgitating something the internet said. people have different ways of doing things and there’s rarely one right way. i hate those fuel line disconnect tools, i have a master set that is 10? years old at this point. ive been in a position at least 100 times (literally) to use the tool or find a different way and it varies by chassis.

in a nutshell - op - quit approaching this like a self confidence lacking high school girl and go get your hands dirty. it’s a gd intake/exhaust manifold removal. probably less than 20 bolts each way. get to it. turn off the phone, computer etc, use some common sense and make the repair. this ain’t rocket surgery.

I've been ready to go with everything but time for 2 days. It's not the computer, phone or anything that I can ignore - it's the 4 year old and 2 year old that never sleeps that I can't and won't just ignore.
I'll be doing it Sat when my parents can entertain the kids. Sorry if that doesn't work for you.

I can relate to that. Granddaughters aged 5.5 and 2. Hard to get anything done.

I hear you - Sat is when I have the time and I'm itching to get it done.
At least 2 pages worth of this thread is good advice that you can't find in the FSM and might be unaware of if (like me) you've never done the replacement.
I can't help it if others jump in with related questions.

Sorry, I don't have the time to read all 4 pages of this, so if it was already suggested... but are you soaking the bolts with PB blaster? I applied almost daily for 2 weeks before doing mine and they came out very easily. For the out of sight bolts on the bottom of the intake manifold, I peeled away a 12 inch section of 12 gauge romex wire sheathing and used that as an extension to the straw for the hard to reach spots.

Good luck.

I've hit them a couple times and will be doing a real good pass tonight.
Fortunately, the bolts I'd be most concerned about - the manifold to front pipe - are a non-issue since I'll be cutting the old front pipe out and replacing it.
