OK first off someone has been in there before, see that cork gasket, thats a no go and was probably leaking anyways,. They dont come from the factory that way and not recommended to use one going forward. All that is needed is oil resistant RTV.
What you are looking at is the windage tray.
Slide a putty knife in between the bottom of the block and the tray and cork mess and work your way around it.
