>Dave Leonard (finally all systems go... no more smoke from the turbo after installing a proper oil return line) 
Excellent. So it was too small a return line?
 
Yes, I finally decided to listen to everyone and install a larger line.  I guess it's not just the ability to return the oil, but I have come to realize that there probably needs to be space for air to pass over the oil within the line.
 
To compound the picture I also make two other changes.  I installed a .110 inch restrictor based on the recommendations of the turbo rebuilder, and I installed a blow off valve.  My guess is that the return line made the difference, but I'll never know for sure.
