Just drop it off at the local Firestone place.







Sorry, just had to.

Don't know on the 4 banger, on my 4.2 the gasket itself wasn't too bad. Getting to it is just a little time consuming. Just see what the Hayne's calls for and make sure you've got time to do it so there's no rush. I went to replace mine and found that my problems were caused by a cracked intake.

Not sure on a 4 banger but on a 6 you need to remove the air box and intake manifold also move the power steering pump out the way.

So its not a hard job just time consuming.

If you still have you original exhaust manifold I would replace it while I have everything torn apart but that's just me.

I would also buy the gasket from the dealer.

Use this stuff too PERMATEX COPPER SPRAY A GASKET HI TEMP SEALANT

Can't with tools for a 4 cyl, I did need for my 6cy 14mm flex head socket and lots of different extensions to get to all the manifold bolts.

Its not hard at all, takes about 2 hrs labor. you will need to remove the airbox and some wires out of your way but its real easy to get to them all. I removed the intake and went ahead with sealing it up when I did the exhaust. my bolts had loosened up over time, I got a 89 and it was the same so I can only think it must be normal for this to happen. I dont think I would use any sealer like locktight cause it may not come out down the road when you NEED to remove the thing.

just watch over what you remove and put it back when you are done, thats all there is to it. good luck.

I'm pretty sure the gasket is an entire gasket, covering the intake and exhaust ports. So, yes...it needs to be removed, or at least "set aside" on top of the engine. I replaced my exhaust manifold, and remembering correctly, the gasket is a complete gasket for both intake and exhaust.


Side note off topic:

Not sure of the context of your signature, but find it rather repulsive.

You talking about the rob99 comment? It was funny at the time, im just waiting for rob to say something else funny so i can quote him.

But do you have to drain the coolant to move the intake manifold?

Yes you do, and I second Tomb Raiders side note as well.

ok, jeepdrvr, tell me why he has to drain the coolant to remove the intake manifold? there is NO coolant running thru the manifold or anywhere near it for that matter.

i didn't drain my coolant... I had a little FUEL come out of my fuel lines on the intake but no coolant. You're not digging into the block, just the intake. And i just unbolted my water pump and just pushed it aside. I also left my throttle body on the intake. Got pics if you need em

No Exhaust Manifold Gasket on a 94 2.5

Guys,

I've fixed a broken exhaust manifold stud and had to remove the intake and exhaust manifolds on my 1994, 4 cylinder engine. There officially is not an exhaust manifold gasket on a 1994. The manifold bolts flush to the engine with no gasket. I confirmed this while at the local Jeep dealer parts department. I'm not sure if other years are different, but if this guy is working on a 1994, there's not an exhaust manifold gasket.

Why do they make gaskets for my jeep then? Are you telling me the gasket that i bought isnt real? I feel like an idiot for buying something not real right now.
