Is the vehicle still running and making the noise? Also, is the engine oil light staying, and is the oil clean and full?
Take a look through this link and see if anything seems to mirror what you experience.
As far as the timing chain is concerned, there are two, an upper and a lower. I attached an exploded view of the chains. I highlighted the sprockets and chain tensioner for your reference. You can remove the cover to see if there is excessive play in either of the chains. Or, if possible, record it and upload it for me to hear and see how it's running (if running).
Also, if you haven't already, remove the accessory drive belts and check for excessive play, drag, or movement in any of the belt-driven pullies.
Let me know your thoughts and what you would like to try first.
