Exhaust manifold oil leak


I was doing an inspection on my van and i saw this oil around the end of the exhaust manifold. Could this be the gasket? Or excess oil spillage? I had an injector leaking before but i fixed it. Thanks for your help.

I have a similar leak just not as severe. I am guessing it has something to do with the EGR. That last runner carries exhaust to the intake side. But I am curious as well.
