ok I know this has probably been beat to death but installing a vortech v1 and i went away from the stock kit and made it a blow thru set up and now i am having trouble figuring out where to run the hoses off the valve covers. i know on the kits intake pipe is where the instructions say they go but different for the blow thru right? I also bought the piping to make my own power pipe so there are no connections on it. I hope what im asking makes sense theres 3 hoses 2 from the passenger side went to the tb and the other went from drivers side to the cai. Thanks for helping

Thats the IAC you have to run that on the discharge tube between the blow through MAF and the throttle body

so reconnect the IAC after the maf and just vent both valve covers with breather filters? drilling a hole after the maf and using a rubber gromet for the IAC works fine?

You can use filters but sometimes it makes a mess. A vented catch can keeps things clean. As for the iac be sure to have the bung welded or use something threaded with a good sealant so it does not leak or blow out

No, once in boost you will blow the hose out. It has to be clamped down.

Ok if you run both vent lines to a catch can where do you run the catch can outlet line to ?

Back to the hole on the plenum that the passenger side vent originally went to ?

The vortech kits only seems to address the drivers side pcv which used to connect to the intake piping just before the throttle body. This connection would not see vacuum.
What about the passenger side that runs to the upper plenum? Without a blower this connection would see vacuum and help to draw suction on the valve cover (unless i have my thinking backwards), but with a blower now it has boost.... Looking at it, it looks like i am going to pressurize my valve cover unless the pcv only flows one way. Should the upper plenum be capped and both pcv run to a can?
@OP. Running to filters is messy and will not pass emmissions.

Yes u cap and run both lines to catch, ur essentially makeing ur pcv system a stand alone system and venting it to atmosphere, they either need to be both ran to catch can or both hooked up, u can't have one hooked up and one ran to catch can/breather or u will b pulling unmetered air
