mr. fuss, welcome to Just Answer!.
There's a good chance your noise is an exhaust leak if:
The rear two exhaust manifold attaching bolts tend to snap on the 4.7 engine, leaving no clamping force on the gasket which opens up a small gap at cylinder #7 or 8 (depending on side). While it may sound like a mechanical ticking noise, it's the exposive nature of exhaust leaving the just-fired cylinder that creates the sound.
On a cool engine, reach toward the back of the exhaust manifold heat shield on both sides and see if it's loose. The same bolts that hold the shield close to the manifold also clamp it to the cylinder head, so if you find you can pull the shield away from the engine... you've got broken bolts.
The good news is that they break off far above the cylinder head surface in this model year, giving you plenty of material to grab for removal. With no torque applied to the threads, they typically just spin right out although gasket replacement will probably be required, requiring manifold removal.
Write back if you have any questions, mr. fuss. I'd be glad to help any way I can.
Exhaust was checked it is not an exhaust leak
The ticking is in the front of the engine by the overhead cam. The noise is quieter when the engine is cold and gets louder as engine heats up. The noise is more prevalent on idle.
I'm afraid I wouldn't be able to give you a satisfactory answer for that noise, mr. fuss. I'll opt-out and return your question to the Open category for other experts to see. Sorry to have wasted your time, but at least we know what it is NOT now!
All the best,
Yes sir. Your question is posted for all Dodge experts again. When someone has an answer for you, they'll post it. Just Answer experts are (for the most part) working stiffs like me, just starting the day. More experts will be online soon.
