No gasket on that part of the turbo.
Everything is machined friction fit.

alright i guess ill give that a try what am i looking for and what should i torque them back to?

[therex]

looks like it was a bad turbine piston ring!

Yep, you can see the black, crusty stuff coming out from under the cup.
If you can had gone one step further and pulled the wheels apart, then you would've seen the mess that's under the cup.
Congrads for getting down to the bottom of this!
Replacing the turbo is a lot better than replacing the engine...

Looking at the non-stock bolts on the compressor housing side, this turbo has been taken apart / rebuild before?

no idea! and funny...i called a guy at a local turbo shop and he said all that cover and ring are used for are exhaust gasses and its most likely my drain line not big enough,thats why its coming out of there

Yes, it's possible that back-pressure through the oil drain line can cause oil to leak past the turbine compression ring back there...
...but we're talking about a stock turbo using the stock oil drain line, right?
Unless you messed up a gasket or went bonkers with the silicone RTV, that's almost impossible...

Part #16 is the turbine compression piston ring that needs to be replaced.
Since these rebuild kits are relatively cheap versus the labor costs, you might as well get the entire turbo rebuilt.

lol no, not stock turbo and not stock drain line...

Hmmm...turbine housing looks stock.
What kinda turbo is it?

What size oil drain line are you running?
Can you take a pic of it?
If the oil drain line is too small or badly designed, it could be possible that "fixing" this problem could solve the smoking problem...
