I am putting 90mm ls2 tb in my 03 z06 and i was just wondering what most of people do with the vent tube that goes to the valve cover? i have seen some people put a small breather to it!! I have got caspers breather that replace the oil cap but i thing it's too big that may his the hood!

That's not the right diagram for your car since you have an LS6 motor. However you're right that there will be that vent tube that you need to do something with. On mine I put a little filter on the end of it sort of like a breather. Then with the PCV line running from the valley cover under the intake I routed it to my catch can and then from the catch can back into the intake.

Here's a link to all the different diagrams (using a catch can).
