I'm just trying to determine if the operation is proper, if I have too much oil moving through it, etc. I just can't find a real test procedure. Seems like there must be some way of checking pressures, blow by, etc.

603 cars in the W126 have an emission air meter under the air intake that silences the intake track quite a bit... combine that with a KKK turbocharger some cars have and they are nearly silent.
What is your other vehicle that is turbocharged? I own many so comparing one to another is difficult unless they are the same make/model
If the vehicle feels sluggish, the the boost lines to the IP get plugged up often on these vehicles.
