Oil leak in rear of car *pictures*

Having an oil leak near the rear of my car looks like a missing gasket that's causing the leak, anyone know what it's called?

The only thing sitting that far back that contains fluid is your fuel tank.
Check inside your spare wheel well to see if something maybe got spilt over and is seeping through there

Agree something must have spilled.

Did some digging around online to find that exact position. Found some underbody images in this post

That grommet looks to be directly below the drivers / passenger (depending on left / right drive) seat. I can confirm that there is nothing there that would leak any sort of oil. I've had my whole interior stripped out while installing sound deadening, there is nothing there but metal, wires and modules.
