And there is a oil catch can before getting vented into the inlet.
Do you think enough vacuum by having the venting into the inlet right after the cone filter. Ill try to post pics later tonight. Basically I have the air filter right on the blower inlet, but a spacer inbetween the two that allowed me to tap to use for the pcv relief.

You will have to be prepared to deal with these issues as they arrise or as much as you can anticipate them. If your engine is built as tight as it can be and your rings seal well then you might get by with the system you are using now. I think it will really come down to how much blow-by you get. If you get none or little you should be fine but as the engine wears you might find you need to do some work to get the pressure out of the crankcase. I would keep an eye on Parish's progress and see how he makes out along with anyone else you know who is running higher boost. If it isn't broke don't fix it but be prepared to make some changes based on your experience.

What about leaving the stock PCV/VENT system alone and installing a 3/4 inch nipple into each valve cover with a baffle under it. Then install an old school pan evac system with a check valve in each down pipe for a twin system or tee them together for a single.
