2005 6.0 burning oil BAD on startup...PCV valve issue?

[farmtruc]

There's a TSB for my '09 Escalade and it was doing the same thing, burning oil. However it wasn't the pcv system, it was the valve cover design.
Anyway, without going into details, I did this instead of buying a new valve cover:

took both valve cover ports to a catch can, then out the catch can into the cai tube so i don't smell any fumes. they get recirculated back into the engine.

Ya I saw there was a catch can setup that kind of looks like an A/C accumulator. I was hoping there was another option rather than doing the catch can setup, or buying new valve covers.
