What's causing this engine noise?
Here's the noise:
This noise just started happening a few weeks ago and is present only when starting a cold engine. It's always louder at first, then gets quieter, then eventually goes away after a few minutes.
Really appreciate your guys' insight as to what is causing this.
Thanks in advance!

I would drain oil and cut open oil filter and verify there's no metal particles. hopefully it's just broken exhaust manifold bolts. any codes? what's the oil pressure?

Exhaust leaks can make many sounds depending upon where they come from. Cracked manifold, loose manifold (bolt broken/missing), loose collector flange, failed exhaust gasket, etc....
I had one on an old Chevy truck that made the strangest clicking sound at the back of the engine, .............. was just a loose header bolt.

Make sure engine has cooled down. Also check for any other broken bolts(passenger side too) while your in there. If it's just the rear, clamp will take care of it. Post update when you get the clamp in place. Btw, how's that transmission performing?
