oil is passing the seals which means your oil pressure is really high or your turbo is blown.

and what seals are you refering to?
turbos don't have seals, reduce your oil pressure, the turbo is fine

The reason the seal bore leaks after a turbo has had to much oil pressure for the size of the drain is:
When the oil can not return to the oil pan it fills the bearing housing up with oil and once it gets higher than the piston ring gap it flows out into the compressor cover and the turbine side of the turbo. Once the drain or oil pressure is fixed the left over oil on the turbine side turns into carbon and we all know carbon is very abrasive. The carbon on the turbine side around the piston ring grove wears the seal bore out as well as the piston ring grove. When this happens the piston ring wears and allows oil to pas by it and leak into the turbine housing. Thats what gives you that wonderful smoking problem at idle.
A simple fix for this to take the turbine housing off and remove the oil from the heat shield or to send the turbo to a repair shop for them to take it apart and do a thorough cleaning. It is much cheaper to do it this way then let it fail and pay big bucks later on.

Turbochargers don't have anything technically called a seal but they do have things that act as seals. They are called piston rings or carbon seals.

they have gas seals (piston rings you are refering to)
and i havn't seen carbon seals since carburation was around

When looking at parts break downs of the turbochargers they are labeled as piston rings. It is listed that way in all the turbo material I have. I have the Garrett CD, Borg Warner CD, Mitsubishi CD, Holset CD. ......
Carbon seals are still used in late model apps also. Look at the twin turbo RX7.
Have you ever seen the carbon seal in the Rajay turbos. Talk about nasty old things. Good god.
I am not a big fan of the carbon seals they create to much drag on the rotating assy.

Carefully with saying that. Just sticking a restrictor in there without confirming the oil pressure that you have at the turbo may cause turbo failure. If your oil pressure is not too high it could be your drain.
Post some pics of your drain set up.
