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.
Ya know, there was a very thin film of oil on the inside of bell housing and on pp. Inside on flywheel face and on pp face it looked dry.
I had a valve cover on drivers side leaking pretty good recently. I should probably look at rear main seal? Ugh
