Exhaust Manifold - clicking

I am told that the clicking noise in the engine (upon acceleration) is coming from my Exhaust Manifold and is a pretty common problem among Jeeps (something about the weight of it makes it crack?).

Well, I do have a Chilton and have looked over the procedure, but I wondered how diffiicult it would be for me to replace the exhaust manifold?

Also, if I did replace it, how reliable is the replacement? Will it crack again?

This is where they typically crack. I would visually check to see that this is indeed the problem before replacing. The APN header is a good replacement and is priced right. Make sure your engine mounts are good and it should last a long time. The reason they crack is because they are unable to flex when the engine moves during acceleration.

Sorry for my ignorance, but what is an APN header?

They crack often due to bad motor mounts. You need to check them as well.

As for changing it, I would rate it a 5-6 (out of 10). There are vacuum lines, electrical connectors, PS bracket, and some hard to reach bolts under the manifolds. Just mark everything you disconnect and take some pictures before you remove anything. Don't forget to use plenty of penetrant (like PB Blaster).

I did mine on my 88 in about 4 hours. But I had plenty of tools, good weather, a concrete floor and a bit of luck that no bolts snapped. YMMV.
