Been learning a bit more about PCV valves and it looks like it's not a good idea to delete the PCV valve or route it to the intake pipe.
Crankcase ventilation system - Wikipedia, the free encyclopedia
As the PCV valve closes DOWN when there is high vacuum (at idle in the std system/position) because there is minimum blowby at idle, if it was routed to the intake pipe then as boost and blowby increased the valve would close down more and more - not what you want.
If the PCV valve was deleted and a straight-thru fitting was used instead to connect to the intake pipe then you might get too much scavenging at idle and other off-boost situations. It might work but would take alot of work to figure out how much scavenging you needed and were getting-not something I could be bothered with at this stage and I wouldn't want to risk damaging my engine not doing this.
So I'll be going back to the std routing below with a catch can on the PCV to intake manifold hose (with check valve added) and another catch can on the T to intake manifod hose (maybe with check valve added there too so that when it's off-boost and the PCV valve is open and sucking air from the T that it only sucks from the crankcase hose and not the catch can on the intake pipe hose).
The slider2828/blue808 mod seems like an excellent mod if you can do it so I'm not taking anything away from them for a moment but since I only use my car on the street I probably don't need it that much either.
(Mmm...maybe I could weld a bung on the REAR of the cam cover instead of the top and hide it that way...
