50 trim in - lot's of smoke from exhaust

[TalonFiero]

When my turbo was going it made lots of smoke when I shifted and at idle, not so much while cruising. I second checking the oil drain line, is it a modified dsm drain tube or custom built? If it is custom where did you get it or if you made it does it dip down below the point of entry on the oil pan? What color is the smoke?
