PP weird spots and uneven face

Hot spots from slipping. Got any fluid leaks in the bellhousing area? Even a drop every now an again can cause these issues.

Or from slipping the clutch a lot on takeoffs.
But yea, oil makes it worse and you can see in the first couple of pics in the center of the PP it's been slinging some.
I would guess input shaft seal on the trans from where it is on the PP.
