So I decided to look for things to fix on my Jeep as does every XJ owner, and to my surprise I found a crack in the exhaust manifold. I'm not really sure if it's a huge deal but could anyone tell me the severity of this? Leave it alone or fix it? I mean I don't really notice anything, I feel a ticking in the valve cover but other than that I don't suspect a thing out of the ordinary. Do cracked exhaust manifolds have any tell tale symptoms?
If you got yourself a welder, just pull the header off and weld it back together along with all the other joints for extra support.
Will run like new if done right.
And then watch it crack in five other places,I have welded my header (seven cracks in all) and now have five more.best to buy a aftermarket namebrand header with a warranty and be done with the problem.
ah,beer the cause of and cure to all of lifes problems ...Homer J Simpson... I am the guy in the red jeep!
Buy a header and a new head gasket set, pull the head and manifolds as one piece. The exhaust is infinitely easier to remove with the entire cylinder head out and it only takes a couple hours to pull the whole thing, change the gasket, and put everything back. Might as well get it all clean and new gaskets in while you're at it.
