Not sure what it is. Thought maybe lifter or tappet(?) or exhaust leak or the transmission and/or engine? Goes away intermittently. Gets faster when accelerating whether on the road or parked in Neutral. Link to video below. Clicking stops at 0:04 seconds and starts again at 0:10 seconds. Then off again at 0:24 seconds and starts again about 0:30 seconds and so on.

I noticed what appears to be some of a gasket missing (starting at 0:06 seconds in and flashlight follows up to 0:18 seconds) and I can see a part rotating inside.
Perspective: I slid under the driver side door and slightly turned so the top of my head is facing the front bumper. The O2 sensor seen is the driver side Bank 1 Sensor 1 upstream.
Oil level is seems fine (I add half a quart every few weeks to keep in the safe zone. There are no obvious leaks and no puddles under the vehicle). Transmission Fluid level also seems fine. Both are good color. Any of this normal? Anyone know what the click is?
