turbos are cooled with oil and that oil is supplied from oil pressure lines. check out the turbo and trace the lines; they should return to the oil pan.
If you look at the TURBO you will see that it has a oil line that hooks to it. The oil seal starts leaking and oil from the engine runs inside of the turbo and makes an oily mess in turbo and Intake hose. Alot of times the engine will smoke out of the exhaust. You need to replace TURBO.
A loud whining noise, excessive oil consumption, loss of power, and a vehicle that smokes can be symptoms of a failing turbo. Also, a failed turbo sometimes leaks oil that can be seen on the body of the turbo, and a failing turbo many times deposits oil on the piping that leads to the throttle body.
you may have another bad turbo, or could even be bad rings with the oil leaking into your turbo, how long after you installed the turbo did it start happening again?

if your turbo is damaged then BIG no. Thru your turbo goes coolant and oil. I've seen dead saabs that got engine damaged because the turbo blew and all the oil leaked out.
