Poor crankcase ventilation as well as excessive incoming oil pressure will both result in too much oil being held in the center housing of the turbo. Failure to repair this will eventually ruin the journal bearings.

It's much more common for oil to blow past the turbine seal and into the exhaust than through the compressor seal and into the intake as the thrust plate prevents high pressure oil from being sprayed directly at the compressor collar. I'd imagine the smoke you're seeing is a result of oil being burnt on the turbine side more than the compressor side.


Moving the oil supply to the head using a 1G oil supply line will most likely remedy your smoking issue as this is the line and oil source that the TD05H center housing was designed to be used in conjunction with.
