2007 Pacifica 3.8L v6
I thought maybe the oil was low, as we've been having an oil leak for awhile that just got fixed today, but the shop filled it up before we left. This just started about a week ago. No lights, no loss of power, nothing.
Sounds like something loose that attaches to the engine, though I can't be for sure what. Due, mainly in part, to the complete blackness.

It's completely black because my phone was right up next to the oil pan to get the noise as clear as possible. It's loudest under the vehicle, so that's where I was. The vehicle was idling in the garage. The noise goes away when the car is in motion (any speed), and can't currently be heard inside the cabin.
It has had an oil leak from the pan gasket and the oil sending unit. The shop replaced the sending unit yesterday, I replaced the gasket about 3 months ago. The leak wasn't TOO bad up until about a week ago when the oil got low enough to cause low pressure light on the dash to illuminate. I put 2 quarts in it to get by a few days; it's completely full as of yesterday.
Pacificas go through motor mounts regularly. Fortunately, we've only had 1 go out, which was on the front. I replaced it the same day I did the oil pan gasket (3 months ago) with an OEM part. I checked it yesterday thinking maybe it was loose, but that came back negative.
