i recently turbocharged my 6.2 with a turbo and parts from a 6.5

there is a breather line that comes from the passenger side valve cover and it is supposed to join into the intake air before the turbo. i'm wondering how important this is, because right now i have the line venting to atmosphere because i don't have all the right intake piping, so i clamped a conical filter right onto the turbo housing and left the breather just hanging there.

aside from smelling oily when idling is this alrite or should i try to get it properly hooked up?

thanks in advance
