From you describtion it seams to me more like valve stem seals, but I can tell my story.
In the end it was fixed by Garett dealership changing whole turbine core and exhaust housing under warranty. They did custom dual oil seal on teh exhaust side for me as they said Cossie engine has turbo slightly leaning to the rear which makes oil gather under the rear seal.
When I had those prblems turbo was leaking so badly there was actually some oil in the exhaust housing all the time so it didn't stop to smoke after being disconnected from oil feed. But at least in theory even with oil feed removed if crank case pressurises the engine can bereath through oil return and smoke through there....
I hope I helped at least a bit.
