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 < 1st 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 / ToyoDIY schematic* / 3rd photo >.

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



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?

Pretty much none of your post made any sense. So many brackets but no proper sentences...

Anyhow, the second pic is what you want. Maybe chuck a catch can in there too while your at it.

Dont put a t-piece in your brake booster vacuum line...

OK; OK; made some changes. . .Not that I can't take criticism but . . . While it's not a paragon of grammar it's not exactly unintelligible.

In any case, the 2nd layout is what I have. Why does the 20V have two outlets while the 16V only has one?

It will work fine then, I would recommend a catch can though.

Also, I think the 20v has the other one to vent into the ports which are controlled by the ISCV. That way both sources of air for the engine have oil venting into them.....Not entirely sure the reason but thats what I figure...

Second picture is right but you will cover the intake plenum and throttles with oil, especially when cornering left. Run a catch can so you don't foul up everything.
