I have a d16z6 boosted and the valve cover hose to the catch can i understand but the second one back to the CAI?will this be efficiant and work as a vac or should i find another place to hook the second hose?

 

back of the block where the black box is i forget the honda part number its off preludes if your just going to use a rubber hose those work if your using an fittings talk to br fittings on ht here thats for b series i dunoo if z6's have threads in that breather hole

 

you can run it from the black box or get the B&R fitting to delete the black box. make sure u take the check valve out . NO u do not run your valve cover back to ur intake and pull nasty oil fumes in ur intake. you run that to your catch can as well. usually run a vented catch can with a set up like this.
