This just started today while driving home from work, not quite sure how to describe the sound, kinda like a mini jack hammer or rocks in a tumbler (attached video with sound). The weird part is: My car runs well aside from the sound, and the sound goes away when actually driving, only occurs when in park, or stopped.

Opened the hood and jacked up the car to try and find the cause of the noise, sounded like it was coming from the engine, or just underneath (there is a box on the underside, not quite sure what it is, but the sound seems to be louder near there).
On a side note, checked my oil, it’s not low. And tried playing around with the pipe leading to the exhaust to see if it was lose - nothing.
Was involved in a hit and run just over 2 weeks ago (front left headlight was smashed, and fender was dented). I’m not sure if that has anything to do with whats happening now, but might help.
Thank you all for any replies!
