You probably had the oil pan off to install the return line. Maybe the sump tube got disturbed, or the oil pressure sender went bad or got some shit stuck in it. Did you put on an oil cooler by chance?? What size feed line are you using to the turbo, and does it have a restrictor fitting on the turbo? I had a similar problem, and it was caused by an oil cooler I installed (the wrong way). I tried to make one out of a tranny cooler and all my oil pressure was going to it because I didn't have a restrictor on it, causing my oil light to come on when the car was idling. I bought a brass gate valve and put it in-line and shut it a little bit, and it fixed it. But I also had a guage so I could see what was really going on, not just the stupid light.
