Can i block this off? What is it exactly

The smaller of these goes to my aos. The larger connects to the other valve cover and I believe into the block. Can these be blocked off or rerouted or something. I'm trying to clean things up as much as possible.

You could re-route but I would not block it off, those ports all work together to equalize pressures within the motor from what I understand.

One port is the blow-by to the PVC circuit. Other port is the crankcase pressure balance circuit between the cyl heads. You could block off the balance circuit but I would not recommend doing so. You are clearly turbocharged and would need both of those on each cyl head.

Most na/t builds just have 1 breather on each valve cover and 1 on the block (stock pcv location).
Turbo pcv setup for the block breather and then T them all together to pull in before the turbo. |

that would be correct for most NA/T builds, but this looks to be either a swap/ na/t with turbo heads and valve covers and not an NA valve cover.
