Wanted to add I think I understand why I was burning so much oil when the the CCV tubes failed. Burning a quart in just 75 miles is just to damn much for sloppy valve guide seals BUT it sounds about right if the crankcase is being pressurized from the turbos thanks to bad check valves in the CCVs and the turbos oil starts seeping right into the intake, path of least resistance and all.

Since I added the catch-cans and using PCV valves as the check valve for the intake tubes, I have returned to burning a quart every 1500-1700 miles which is pretty damn good for this engine and how I drive (I average 200-300 miles a day, and it hits 110 mph+ nearly every day....gets boring coming home at 3am......"but officer, I was only driving 110 to stay awake..."
