Wasn't there a number of posts a while back when a lot of people started getting the latest line of Garrett ball bearing turbos like this? If I remember correctly it was found that due to the lower lubrication requirements of the updated bearings the stock sized restricters in the oil lines were feeding too much oil to them, causing said smoking problem? Further memory serves to say SPZ solved with with their stainless oil line kit that uses a smaller restricter bolt.
