Almost looks like blow by gases coming through the valley cover gasket or front timing cover gasket right above the water pump. Your PCV plugged or the vacuum line between the PCV and intake broken?
If you take off your oil cap does the smoke come from there as well? Looks like crankcase gasses to me maybe?
How is your PCV system setup?
I'm thinking crankcase now too. The breather is smoking like crazy now. Thinking my rings are shot. I have a hose off each valve cover running to one catch can/breather.
Yes the smoke comes out like a train with the oil cap off, but stops smoking from the intake area. Smokes so bad it fills up my garage with 2 does open.

Yeah then it's definitely crankcase gasses/blow by. When you take the cap off it gives it somewhere else to escape from.
Sounds like rings/ringlands unfortunately I would try a compression test, and then another compression test with a little bit of oil in each cyl before you tear it apart though. May be something simple.
I just did a compression test a few weeks ago. I've owned the car just a few months. For the past month its been having problems. Finally got it running decent.

PCV needs vacuum to work. If you are boosted, you might not be getting vacuum to your PCV, so the gases build up in your crankcase and find a way out anywhere they can. You probably need to be drawing vacuum from between your air filter and turbo if you aren't.
Also, verify the hoses are intact and the valve isn't plugged or stuck
Looks like you have nothing pulling from the crank case, so your PCV is not doing anything. Try this equally crappy drawing for what should work to fix it. Eliminate the hose with an X through it. Add the yellow and orange hoses. The orange hose should connect between the filter and turbo for vacuum. You will need a one-way check valve in the yellow hose to make sure the airflow is only toward the throttle body
No that is suppose to connect to the passenger side valve cover. It looks like to me the entire PCV system has been deleted or something. Google "LS1 PCV System". Plenty of diagram pics out there.
