Still have oil consumption... Yeah I've done some searching, but it's just easier to post my problem + my combo and see what y'all might recommend. 99 WS6 that I drive daily. Last spring I did an LS6 intake swap along with the new LS6 valley pan and catch can because I was using oil. I didn't have any issues over the Summer but now I'm back to using about a quart every 3000 miles. The catch can is bone dry. Tomorrow I'm going to pull the lid off and see if there is any oil in the TB, but I don't really think there will be. The car doesn't smoke and runs a strong 45psi oil pressure at idle and ~70 at WOT. Sorry for the long post, just want to give as much info as I can off the bat. Thanks for the input.
Not an LS1 but with my old pontiac 400 I was using oil. No leaks, no visible smoke and catch can empty. Changed the valve stem seals and it stopped. The only sign of oil burning was a higher than expected hydrocarbon count in the exhaust gas. Bottom line is, it's either leaking out or being burnt in the combustion process.

Youve got it hooked up wrong.
The bottom nipple of the catch can needs to be hooked to the intake manifold nipple (this is the dirty line).
The throttle body nipple (this is the clean line) needs to be attached to the passenger side valve cover.

Man I really appreciate that. I guess I did misunderstand when I was doing my research before installing everything. I've got an opportunity due to the holiday to get alot done to the car this week and fixing that is at the top of the list. Thanks again.

I already fixed it. I've got the headlights tore apart right now dealing with some issues there. I'll have to drive it for a while before Ill know for sure. By chance, do you think there was any HP loss from having it routed wrong? I smoked a Coyote the other night, LoL. Just curious if I still had more on the table.
