Dropped my pan and found all this. Any thoughts on what it could be? Gasket was starting to leak at the rear and so I went ahead and cleaned all this up and replaced it. What a PITA putting it all back in but got it. Oil was getting to all the right places and pressure was good but this couldn't have been good for the oil pump. Driving fine now, no change in oil pressure or anything so relieved but not sure if anyone has seen this before.
