i know theres 100 threads on this and a 100 answers’ I picked up a Moroso Dry Sump Breather Tank (Oil Catch Can). This is how Im thinking about hooking it up should I just eliminate the PCV valve and run a T valve IM to catch can to black box, or not ..... this for a d16

 

If you run it like that won't the car run like it has an vaccum leak because of the vented can? I could be wrong.......

 

Yes it would act like a big vacuum leak. In order for your catch can to work in this vacuum style system you will have to remove the breather element from the catch can and close off the open fitting.

 

Or run this can-
