Crankcase noobie here, so I appreciate your patience. Which of these setups is correct when preparing the crank case for big turbo? (gtx2971) I've been reading into crankcase ventilation setups for hours and these 2 seem like the go-to's. Do we have to send fumes back into the intake manifold and turbo inlet? Would eliminating the sealed catch can be a possibility or is it there for a reason?

I'm assuming the option 2 vacuum leak is tunable?
