Was it leaking before the rebuild too?

First thing to check is the drain tube going from the turbo to the crankcase. Make sure it's wide open and ready to flow some oil.

Also a common mod is to remove the closed crankcase breather system and switch to an open breather. This will eliminate oil ingestion at the comp inlet.

High crankcase pressure will also cause the turbo to leak into the comp out. But that's a bit more dificult to check. All you can probably do regarding that is make sure the crankcase is vented properly and that the PCV valve is working well.

Is turbo for a hot air car? I think you need different compressor seals to hold in oil when TB is closed. Big vacume in that turbo, could be sucking in oil. 86-87 don't have that problem
