leave the valve cover alone, hose from the intake piping to the valve cover.. no breather, etc.

Re: PCV valve why??? (StyleTEG)
How about the sizing of the vents?
the valve cover vent and the block ventilation vent.
Is it just moderately sized to fit all rev ranges? I see the higher rpm motors having more equal size vents in the head *edit valve cover*, but no changes in the block vent. Is it just for the simple fact that altering the valve cover is better than altering the block?

it's easier to understand when the engine is N/A but what if you were turbocharged? does the pcv get shut off by the incoming boost? if so, then on an FI car the pcv only works if there's no boost yet correct?
i was thinking, connect a hose from the valve cover into the pipe BEFORE the turbo but what about the pcv? if you just connect a catch can between pcv and IM would pcv valve still work during boost? unlike in N/A the pcv valve doesn't get block coz there's no incoming boost even at WOT.
i wonder if this diagram is the best alternative for FI...

what do you mean pcv will pull a vacuum on the crankcase? what will happen if it pull vacuum on the crankcase?
