All the above, check the Power steering hoses/clamps and pump for leaks also (could be both engine oil and PS/ATF fluid) or just the oil blown
all around, which it obviously is.
Ditto: do what FJ80 Oregon recommended, you need to wash/clean that whole area off well then check it after a very short drive (or let the engine idle for awhile while drying off) then watch where the leak(s) show up first.
If it turns out to be the oil pump cover do a search for "Oil Pump Cover Leak", been discussed a lot in the past but often it turns out as mentioned above, all of the above sources if the engine seals/gaskets are original.
