Why does a bunch of blue smoke exit my exhaust.
If I sit idle for longer then like 10 minutes if I rev it theres a shitload of blue smoke what does that mean? I did notice that my oil consumtion did accelerate a lil bit. My poor ol ls1 on it's way out?

you sure its blue? how many miles are on your motor? sounds like bad rings or valve seals
EDIT--- do a compression test, and a leakdown test on it...should help you solve your problem

i have the same problem. lately ive been driving more responsibly. so i never see or smell the oil anymore.
although last night i was cruising around and i was at a red light under the freeway and we all know how sexy LTs sound at 5k in a concrete enclosure so i gave it a few clean revs and damn! my car just bellowed blue smoke for like a minute. it was bad!

I agree with the valve guides as the problem.
Normally if you see puffs of blue smoke after starting up from a stop or idling - it is the valve guides.
If you see blue smoke all the time while driving it is rings...

Try doing a Leak Down test.. It should help isolate where your leakage is coming from ?
Have you checked your PCV system, could be the pcv is leaking oil into the Intake.?..
What year is your car ?.. early LS1's have bad PCV system/Valves.. swap in a newer style PCV Valve or upgrade to a LS6 pcv system.
