Do the 4.7L have the MDS system? Not sure if that is the case but they are problems from what I read.

Maybe do a compression test to find if a cylinder has dropped compression, in some cases I have seen the valve seat drop and start a slight tick and end up breaking it into little pieces and destroy a very good engine, just a thought.

My wife's 300 with the 5.7 hemi was like that ( the way we got it ) I am rebuilding another engine to fix the problem.

I have the 4.7l and it only happens when it gets warm and then it is constant

After it warms up and ticking take the accessory belt off quickly and remove it and start it just for a few seconds and see if the ticking stops. If still ticking then it is in the engine ( at least it is a starting point to narrow the problem down )

Oil in the 4.7l was a issue also for sludging up and causing problems.

My older brother swears up and down that is a hydraulic lifter or a rocker arm or a broken valve spring but I have replaced all of that but not the valve springs you would think that it would stop making the noise after it warms up but this does when it warms up like when the oil gets hot

It was right after I changed all those parts and I took it for a test drive and I had to get down hard on it because I pulled out in front of someone and I did not want to get hit

You should hook a mechanical oil pressure gauge up , to see what the pressure really is ? Maybe it’s your oil pick up screen in the sump that clogged or gummed up with sludge, you got on it to save yourself and others , thus starving engine of oil at sustained high rpm ? Or not

Passenger side and to the rear but it is loud and can hear it best under the truck at the bell housing I have a stethoscope and the noise is loudest at the bell housing
