Can i unhook where my BOV line goes, and hook it to the right side like in the previous picture. Then connect the right line(on the block) to where it originally went into the block. And connect the boost gauge line to where the BOV line went..
That is just a tube that goes through the cam cover. It can be left open, but is there to send a vac/boost signal through...so you dont have to run a vac line all of the way across the engine bay. One side connects to the intake mani (to get vac/boost pressure) and the other side can go wherever you want...mine went to the bov (which is where most peoples go).
So to answer your question, yes, you can cut the blue vac line. Run the one side from the intake mani into the drivers side of the cam cover nipple, then run the other half of the vac line from the passengers side of the cam cover nipple to your bov.
