can someone explain to me the best way to vent a valve cover for a turbo vtir setup?

Can't be good for the motor though as the valve cover should not see an vacuum caused by the boost pressurising it.

I think he means running the breather back to the pipe before the turbo ("the intake pipe of the turbo"). ie: creating a vacuum. not to the pressurised pipe after the turbo.

3 point outlets catch can between the Value cover and the normal location

Value cover to the top the catch can and the size outlet to the other normal spot

last - bottom catch can outlet plumbed to the back of the block

Must be a closed loop for street use
