5.2 no exhaust manifold gasket?

Is it true our 5.2 has no exhaust manifold gasket? If so I wonder where this damn exhaust leak is coming from on the rear pass side of the exhaust manifold. I saw something on another forum about a gasket for the EGR tube. Anyone else had this problem?

I cant see what year your Jeep is on the mobile phone, but 96+ did not have the egr system. On my 95 I did have a leak where the egr tube bolts to the exhaust manifold. $3 gasket at the dealership and all was good again. Kind of a pita to get to, so I ended up bending the heat shield back a bit to get better access.

Also, there should be an exhaust manifold gasket. I have seen them on summits website.

No exhaust manifold gaskets from the factory.

I guess you could use one, but that's adding a point of failure.

If the manifold has warped then maybe a gasket would help. Never heard of them warping.

Yes it could be the EGR to manifold gasket. Try using a stethoscope to nail it down.

When I swapped motors recently in my ZJ (5.2), I noticed my 96 had a EGR system. So I finally got the motor out, looked on the back, "CAS 4/15/09. "

Had a 93-95 motor put in by the PO(I got super pissed when I found that out)...so now I have a EGR system that had screws in all the vacuum lines so they're plugged. That's how I found it, that's how I'm leaving it. That EGR line from the manifold to the intake is a major pain in the *** to unscrew. So easy to screw in though.

I did put exhaust gaskets on when I put the manifold on the new motor. Hopefully they won't fail anytime soon...

Yeah the leak i have isnt bad. You can see some carbon back there from wherever its coming from...and you can hear the annoying ticking sound from it. Once i get it from nc to california and get all settled in I'll work on it.

Metal to metal is best with the stock manifolds. A gasket should not be used, it can cause failure due to less efficient heat transfer and differing expansion rates.

Dang. I'll try and loosen some bolts on the manifold and pull them out then.

Its just that Jasper sent a whole gasket kit with the new motor.
