Yeah, I removed the jug and set it aside. Def seems ok.

I looked again and it seems like the coolant is coming off the heat shield above the exhaust at the very back of the heat shield. So agree probably coming from somewhere forward. Right now I see no other leaks.

I don't see any issues by the expansion tank. Could very well be below the intake manifold. Oh boy!
