BigPort 16V+ Quads - crankcase ventilation

[GeeEss]

Attached photo < 16V+Quads_1 > shows my current crankcase ventilation layout. (I am running AE101 Quads on Bigport AE92 16V; have A/C, Psteer).

I tried to replicate Blacktop 20V layout < picture> but Dyno guy said that this was incorrect and that as 16V had only 1 ventilation outlet on head that this ventilation hose should run to a point behind the throttles < @ orig TVIS layout / see ToyoDIY schematic* / 2nd photo >.

I just wanted to confirm this was correct before changing vac layout. I am either going to;

1. Insert a Tee piece into Brake Booster line & run off that or
2. Run to a 2nd 3/8” union on RHS of Manifold (behind throttle on #4 ITB or
3. Insert a new 3/8” union into inlet Manifold directly underneath existing Cam Cover Outlet < 16V+Quads_2 >

PS: Looking at ToyoDIY schematic; my engine doesn’t seem to have a PCV valve (Valves are listed as “Non Applicable” in index). Can anyone advise why this is the case?

The GZE's vent to the atmospheric side of the throttle body, so that's something to consider.
I've seen other crank case ventilation systems that vent only to the atmospheric side of the throttle body that use a tube that protrudes into the air stream.
I believe that the protruding tube cause a low pressure area (like a venturie in a carby) when the incoming airflow is sufficiently high and helps the crank case gasses exit. If you look at 'pan evac' systems, they work on the same principle (gasses having to speed up as they flow past/through a small restriction) past, but they vent the gasses into the exhaust.
