Okay, so i was just routing around under the bonnet today checking out some stuff and saw what looks like oil leaking out from around a seal on the manifold.

Where the purple ice cream is is where i found this oil leak but was confused as to why there is oil coming out from here? :s

Closer look as you could probs just make out is some sort of oil leaking. the top part is bolted onto this next bit which i dont know what it is ( sorry for my complete lack of understanding with this part of the engine ) that is where the leak it. does this mean i have to replace manifold, or just the gasket? or exhaust? or what lol
Cheers for any help in advance
Edit: sorry the pink ice cream ahsnt shown but its where the manifold is
