Look at diagram, hose #4 goes to oil pan.

Right. Did your 3.0i intake manifold have that oil pan hose attached? Mine did not, only the one coming from the valve cover.

As per vin check, year (make/model) and realoem I have a n52. And the donor car N52 (a E60 530i) intake manifold fits like a glove.
