Is it white bluish smoke? or White steamy smoke?
If it's bluish it could be your turbo oil seals. If it's white steamy smoke it's coolant getting into the combustion chamber typically. This will only show up in a radiator pressure test but more likely a better test is an actual leak down. Hope this helps.

Could be blow by... but it seems your compression numbers are okay.
Check the rubber gaskets around your spark plug wells; and ensure your valve cover is torqued at the correct value and peoper order per the FSM- this could be the culprit. Also verify your PCV valve is functioning properly. It should rattle freely when you shake it. If it doesn't, you can immerse it in gasoline for 15-20min, then repeat until it rattles freely when shaken.
