If I let it sit and idle for more than 5 minutes I will start to see wisps of blueish-grey smoke and puffs when I rev. Yesterday was an abnormally long idle (more than 15 min.) period because I was tweaking the idle-dampener and I saw much more smoke (big plumes when reving, steady wisps at idle) and noticed the oil loss(greater than 1/2 qt). Thanks again.

My conclusion is that the turbo leaks oil at all times. However, at idle, there is insufficient airflow to move the oil to the intake manifold and it pools at the turbo outlet. When airflow is increased, this large amount of oil will head toward the cylinders and generate the increased smoke.
If this conclusion is valid, the oil consumption is present at all times............not simply when sitting at idle. I question the validity of the data regarding the oil consumption.
