Check valve is in. I was able to reroute my oil return lines too since I’m no longer using the sump, looks much better under the vehicle. When I disconnected the return line coming out of the base of the turbo, I had ~12oz of oil come out, which would certainly explain why I’m still getting so much smoke out of the tail pipe. So hopefully all this makes a big difference.

First picture is the elbow right after my muffler, gives a little bit of an idea of how much oil has been getting pushed though (and how many pin holes in my weld joints).

Second picture is my intake pipe going into the throttle body. Hopefully these changes make a difference in that too.
