Look down into the riser from the compressor wheel and see if the oil begins to accumulate in this area............you'll see it start to pool.

If no oil appears within five minutes, you can be certain that the oil is not coming from the turbo's oil supply. Yes, I do realize you just replaced the turbo.............but, quality being what it is today............you've got to check it out.

If the oil was leaking past the head gasket into #1, you'd get a small leak at idle ...........and it would be greater at higher rpm's when the pressure comes up.

The smoke caused by the turbo is dependent on airflow. At idle, with very low airflow............you get very little smoke. But, the oil pools at the compressor wheel and, at the moment when you open the rack............look out.
