Hey guys, just to let you guys know I FINALLY HAVE A JEEP! So yea I'm new here and found an a pretty good xj for the price on craigslist. I've been doing some maintenance and my jeep has that annoying tick that many people say comes with the jeep 4.0 engine. However there's many things I've heard can be the issue: lifters, valves and of course the exhaust manifold. I've run seafoamed and it seemed to kinda help a little but not really. I just changed the oil and add marvels mystery oil and that kind of helped too but not much and then I went offroading and well now it's louder than it's been haha but here's a video I took of it. Can anybody help me???

 

Turn the stereo up louder.

 

possible exhaust leak. a good sized one too.

 

I just had it inspected and it passed exhaust emissions, wouldnt a leak fail it?

 

I had a rusted hole in my tailpipe and a crack in my manifold and i still passed.

 

oh well dang, is this what your manifold sounded like?

 

Well it is a lot louder then when i first bought it but i mostly i can only hear a little metallic sound which i dont even know if thats the mani fold.
Not worried about it too much but keeping my eye out for a new manifold.

 

... But no i dont hear a tic from mine.

 

No. You have less emissions with an exhaust leak because you have less exhaust making it back to the tail pipe. Check where your manifold bolts to the crimped pipe.

 

Am I looking for a crack or a loose bolt?

 

Loose bolts

 

Alright thanks. Just making sure your talking about where the exhaust manifold runs into the exhaust pipe? Not any part coming directly off the motor?

 

Yes.

 

Well I think I found my problem...
Is that a crack?

 

Were do u think u see a crack at I dont see anything
