Interesting Catch Can Routing Motor is a 2002 Ls1 with non Ls6 pcv... I have a question about routing a catch can in the following way:
Run a valve cover oil cap adapter on passenger side valve cover and connect one line to that port... Other line will go to the rear driver side valve cover... Sound like it will work? I cant find anyone else running it like this... Below is the catch can setup... Let me know what you think...

It'll work as a vent, that's all. Adding a PCV valve won't accomplish anything 'cuz there's no vacuum source with that arrangement. If you are only looking for a crank case pressure vent, it's OK. If looking for a PCV circuit that moves fresh air through the crank case, it won't.
If you want a PCV circuit, use a PCV grommet on rear of driver side valve cover or in a line you run to the intake (opens toward intake). Put a T in the line that runs from the catch can to rear of driver side valve cover & run it to the intake. Also, need a fresh air source from filtered air. Run a line after MAF to passenger side valve cover. Note: because the catch can has a filter, there will be unmeasured air entering the engine once you connect to the manifold (unless there's a check valve in the catch can). This isn't a huge deal, but, it will lean out the normal driving mix a bit.

In general, yes. Metered (comes from TB nipple tht takes filtered air after MAF) fresh air source to passenger side cover. PCV valve mounted in a grommet, rear of driver side valve cover. Connect the two valve covers together w/an in-line T. T'd line runs to intake manifold w/ catch can installed in the line.
It will work w/ the filter in the catch can, but won't be as efficient @ moving air through the crank case because the system will also be pulling air from the catch can that doesn't run through the crank case; unless there is a check valve in the catch can that blocks ambient air from entering the catch can, but opens to allow pressure venting.
