Default LS2 PCV Routing

I need to check the routing / operation of the PCV system on a 2007 LS2, but the manual I have access to is for 2003 models. Can someone tell me if the LS2 system is routed exactly the same way as the LS6? (I know the LS1 is different.)

Thanks in advance!

Thanks...The reason I am trying to verify the routing is I am trouble shooting an LSX 455 that is consuming a quart of oil through the intake every 200 miles. Here's a link if anyone is interested:

Got a new question about the PCV "valve" on these motors:

Is the PCV "valve" on the LS2 / LS3 an actual valve in the traditional sense? I am trying to determine if one is working properly.

Most systems utilize a ball-type check valve and are functioning properly if you can suck air through but not blow air out of the attached rubber line.

Does one check the LS2 / LS3 PCV's mounted on the valley cover in the same fashion? If not, how can you determine if it is functioning correctly?
