Hello Guys:

im struggling trying to find where a vacuum hose is connected to,
its a s40 2005 turbo
Lower intake manifold has two brass connections for vaccum, one I believe goes to the oil trap, and the other one ... can’t recall where is connected to?

can any generous soul help me on this Odisea please

Thank you very much
