Hi guys,
I just bought a N52B30 which com from to a Z4 3.0si to put in my 325i e90 N52B25 MSV70 and i have some questions if someone could help:
First, the intake manifold which was on the Z4 is this one and i would like to know if it's the right one for the N52B30 because there is no DISA valve on it :

And after, there is no oil pan return from the PCV on this engine, does someone have an idea about the PCV system in this case ?








Thanks
