Rattling from under the hood
I would start by splitting up the drive train to determine if it is accessory, engine or transmission related.
There are a number of things that can cause a problem like this.
1) Is the noise louder in drive or reverse.
2) I would start with heat-shields because of your "clank" description. Exhaust manifold, catalytic converter shields and any other you can find under hood or under body.
3) If all is good, check engine and transmission mounts. Make certain none have collapsed, cracked or broken.
4) If all good, remove all accessory drive belts and start engine to see if noise goes away.
That's a lot to start with, so let me know what you find and we will go from there.
Regards.
