Need to Vent?
Need to Vent? I am installing new CF Valve covers with no vents on the passenger side cover. I got the PCV problem solved and will install new LS6 Valley cover. What is the answer for the line coming off the Throttle body to the front vent. What do I need to do?

If your refering to the one that goes from tb to the valve coverall it does is deverts some incoming air into the engine to help with the pcv.I didn't like the looks of the pipe sticking out with a cap on it so I cut it off and filled it with JB weld then sanded and filed it after it set up.A dust cap will cap it.
This is one reason I don't like the CF valve covers on the market. You could install one of these in one cover and use an AN fitting to adapt and connect to the TB.
Here's a good thread discussing PCV routing and catch cans.

I understand, but if you need it you need it. Not much way around it unless you just vent your crankcase to atmosphere and delete the PCV system. You could run an after market vacuum pump system but that would require even more holes that are larger in diameter.
