No pictures of that, nothing fancy, just a bunch of aluminum.
My exhaust has always had an annoying leak in it, but because it didn't hurt anything, i never really bothered to fix it. I had ordered a new manifold right after i bought the jeep, and being bored today, decided to pull out the old one and install the new one.

Bare block.

I'd say that's a crack haha

184k miles worth of crud built up. I cleaned it all out, but there was some carbon buildup on the valves. ANyone have reccomendations for cleaning that without pulling the head? i.e. seafoam, etc.

New 3-2-1 manifold.

Annoying exhaust leak is now gone, but it has a high idle. I can't find any vacuum leaks, so i'm going to continue hunting and see what's going on. Drives fine, just runs at about 1000-1250 rpm at idle in neutral.
