408 and STS needs some PVC help.. I removed the PVC, put a breather on both valve covers,and plugged the throttle body.kinda confused on what to do next.
what port goes to the inlet on the turbo,Can I run a breather and a check valve on the intake manifold port?
This is the last step before I start driving it around
can't wait!

Nice 
But don't think thats the right set-up for me? I don't have an ls6
valley and I have a breather in the oil fill and one in the driver side rear cover where the pvc went before.
What do I do with the intake manifold port?
Can I do this without a catch can?

What about this?
line from intake to valve cover(or crankcase) w/ 1 way valve and oil separator
this is a vacuum source to pull air (and a slight vacuum) through the engine when out of boost, and seal when in boost
line from valley cover (or crank case)to in front of turbo/(sc)
this is a vacuum source to pull air through the engine when in boost (low presssure area btwn air filter and turbo/(sc)) and a fresh air source when out of boost (see above)
large home made 1 way valve on valvecover (or crank case)
this allows any positive pressure that may develop to escape quickly and easily
