The short answer is no. You cannot remove the cylindrical unit. It is part of the pressure control system and contains a spring and diaphragm attached to a valve inside of the body of the turbo.

I had the same problem with my 82 300 turbodiesel. There is a procedure to remove the oil return line without removing the turbo, but believe me it is wrong - at least for the Garrett turbo.

You could check this on yours by removing the bolts on the oil return line flange. Although you cannot see them, you can do this from above the car with flex sockets. Once the two bolts are removed, you need to rotate the flanged section 180 degrees in order to be able to have enough clearance to separate it from the lower tube. This is where I ran into difficulty as the cylindrical body of the control valve actuator inteferred with rotation of the upper oil return line.

The only way to separate the two tubes is to remove the turbo. I am in the process of doing this now for other reasons. See my last post for more info.
