1.8T AMB Front main seal?

[GTA]

While doing a flush and fill of coolant and power steering fluid, I noticed this leak coming from the front crank. Obviously, there's nothing else it can be other than engine oil. But it's black and baked on the oil pan and hard enough that I would have to chip it off. Even brake cleaner doesn't seem to remove it. My engine oil doesn't look that black on the dipstick and I've never seen engine oil go that hard before.

Whadda ya think? Front main seal? Or could there be something else above it behind the plastic timing cover that can ooze this out?

Can this be caused by clogged up PVC system? My car had been running kinda rough on cold startup over the last few months but it never stalls and I haven't looked any deeper into this issue. Also no check engine light is lit and I haven't scanned it yet.

Sorry for so many dumb questions but I would like to know if they can be related and tied into the PVC system.
