Cracked manifold or not?

Hello Folks
I still haven't found out where the nasty exhaust "tick" is coming from in my '95 YJ. After posting a question about it before, and hearing from others that it was common for the rear manifold bolt to break off in the head, I decide to take it to a shop and have it checked out. Without looking at it, the mechanic said, "Yup, the rear exhaust manifold bolt is probably broken off in the head, and now the manifold is warped". But after an inspection, he came out and said that the bolts were fine, and not broken. Anyhow, now I have it in my head that the manifold is cracked. Any thoughts? It leaks/ticks for the first while after you start it cold, and then goes away when its warmed up. How can I tell if its cracked? Is it common for the four cylinder manifolds to crack? A girl at work told me today that her '98 TJ has been in the shop twice due to manifold problems...but she didn't know any details. Any advice would be appreciated. I'm gonna change it myself, but want to know for sure that its the problem first. Thanks.

When it's COLD, just use you hand to feel for air pulses. Might even disconnect the fan belt(s) so there is no extra wind.

Re: Cracked manifold or not?

There are issues with the exhaust manifold bolts/studs breaking/cracking on your engine . There was also a TSB issued from DC about this .

Re: Cracked manifold or not?

The exhaust manifold for the 2.5 of your vintage is cast iron and does not have a "doughnut" (gasket) between the bottom of the manifold and the start of the exhaust pipe. It is metal to metal. Check that connection as it may be loose. Also, you may have a leak at the intake/exhaust manifold gasket. They are one piece for both manifolds.

If your manifold is cracked try http://www.bishopengine.com/pages/ei...oductid=C-1532 I have used these guys before and was very pleased. The Jeep dealer is going to get you about $110 plus for an OEM part.

Good Luck!
