Lifter tick or busted header??

A friend has a 2006 commander. On the right side of the engine is a ticking sound when he starts it up. The warmer the engine gets the quieter it gets at idle. When driving it gets loud again. I'm thinking its a cracked header but not sure. Anyone else ran into this. I'm not to familiar with the commanders. I have a 96 ZJ

I am curious on this too. I have the same symptom on the passenger side of my 2010 5.7hemi. It sounds like an exhaust leak and basically disappears once it warms up. Is this a common problem on the Hemi? Why is it happening, broken studs, bad gaskets, cracked manifolds? I want to repair it but want to see if there is a known issue.

After looking into it I'm thinking that the exhaust manifold bolts are a common problem with this 4.7 engine. I guess people are having problems with them breaking and the manifold warping.

If you take out the fender well liner, you can see some header bolts. I had one or two that were completely sheered off. Caused a ticking sound. Sound was gone when bolt got replaced.

Pop the hood with the engine on and smell for exhaust fumes

How is everyone getting the broken bolts out? Having to drill them out or using an easy out? What is everyone finding the best way to do this is?
