Well for the now the problem is fixed. I swapped out the VVT cleared the codes and ran it through the gears and hit 3500+. No longer in limp mode, both codes have yet to come back, and the ruff/weird idle is gone. For now...

Still concerned with the buildup just below the VVT case cover, on the coolant hose attachment. Hopeing it's from the VVT or gasket I just replaced.

If **** happens I'll update.

So check you're VVT if you get a P0300 +/- P0021 codes.

~Small Update~
Drove it around for a little yesterday, a little spirited driving included, everything is holding up so far. My theory is it that possibly due to the cold oil and overall temp on an old part, the sudden increase in pressure caused it to fail.
