Closeup of the oil return for the turbo. Not sure if it was a bad casting or a bad design... but I couldn't get a socket onto the bolt head to get the bolt out, and getting a wrench on that thing while the turbo is still in the car just isn't practical. Anyone that's done these before knows *exactly* what i'm talking about. So, I took my handy-dandy Dremel tool with a nice metal carver, and carved out a good chunk of whatever that metal is (aluminum i think). socket fits nice now.
