There is a sock. I know because I've changed them. It is an older design of environmental system like the A319/20.
The smell is not just oil, it is also mold, probably black mold because wet gym socks is what Black mold smells like. I know cause I've seen that too. There is always moldiness on and around the sock area, because it's always damp and it should be changed weekly but it is not required to be changed by regulations, so it doesn't happen.
