I have been suggesting this all along, as it is the only way to test the seals in the turbo. No need to attach any kind of hose to the drain tube. The turbo will rest on the drain tube and be held in place by the oil feed tube. As long as you don't drive the car around and just test it while parked, you should find out right away if the turbo is bad.
