What is this engine part?

This is probably a very simple question, but what is this on my V8? I didn't see anything about it in the literature. It appears to contain oil and drain into the intake manifold.

My understanding is that the vented cap next to it is the oil filler cap, so I'm a bit lost as to the purpose of this.

Thanks
