Yes I suppose you'd have to change the plumbing to the cam covers else thats the path the oil will go - but It seems fresh air venting the cam covers and switching the big "Y" throttle body connector over to the filler neck could be a minimal system.

I think John answered the other part - early perimeter gasket underneath + RTV/Slicone and the 32V stock O-ring seal above.

The venting I assumed to be via a Provent - with the big 3/4" - 1" feed (like DR's extreme system). I posted on rennlist about the overall system I envisage (on the DR 'sharkvent' thread). I see this oil scrubber and a Provent as a great combo system. I do think with these two in series the provent output vent can be scavenged by all the existing 3 vac lines back into the intake (should be pretty clean), would need to replicate the restriction to the intake vac and a check valve for the big "Y" port. Then I'd go with fresh air only venting into all 4 cam ports (e.g. add one DS) fed from the filter box - for unidir drain flow.

I am feeling like I finally have the right plan for this...
