Isn't it next to the auto-dim mirror oil pump? ...
It's the black disc-shaped thing that plugs into the side of your Y-pipe (on most models, it's a little different on each one) towards the J bend.
The diverter valves (2) are just to the left and right of your throttle body boot.

Question about that "non return valve". Does that valve close
under boost to keep boost from going into the "distributor piece"? I know it has a spring on it...just trying to figured out how it's truely working. Cause I'm going to try something soon to see if I can eliminate the F-hose.

No, it is sucked closed during vacuum/pushed open during boost.
When you are on boost, the crankcase vapors are directed into the y-pipe and through the entire intake system (hence the oily residue in the BPVs, ICs, etc.). When under vacuum, crankcase vapors are fed though the F-hose directly into the intake manifold.
The other branch of the F-hose takes in fuel vapors, which are also directed to the intake manifold under vacuum (under boost they travel along the turbo inlet pipes and enter the intake just before the turbos).

I don't think so. It is sucked open by manifold vacuum against its spring. It's closed during boost.

That's what I was thinking. If it is that way, you might be able to cap that valve off and
then just have hose doing to the connection that is in the intake manifold. No more F-hose. ?????
