Slip fit with -AN to NPT adapters on both ends, and it's tapped into the block above the pan. From everything I've read, I am damn sure this is my problem. T3's do not have oil seals, but rather piston ring type rings. I'm not dorwning my turbo in oil because of the feed, but because it simply can't drain fast enough.

Thanks for the link, I'm going to order a return line from them today
