Ok,
So I guess I'm permanent member the "oil consumption past the turbo seal" community with my GT35R.
There is no oil consumtion at vaccum (checked before and after 500 mile trip).
There was lots of of smoke from day one ,"clocked" the turbo and i could not see it anymore... However on trackDays ,after a little less than 50miles on the track I'm loosing more than a quater of oil. Today I got a few onBoard videos from my buddy's M3 ,and here is my launch:

It does not smoke always ,but from time to time it happens. Now I've spend 2 days and could not find any info from "the Great Garrrreeeettt" about the recomended Oil pressure at the turbo inlet (past restrictor) ,I wonder why I spend the $40 for the plumbing from ATP to measure it ,when they have no idea what the pressure should be!
I would either dump the Ball Bearing turbo ,and get some old school unrestricted turbo ,or solve the problem
For now I got a few LS1 smog pumps ,progressive vaccum regulator and would try to pull some Vaccum in the PCV and report the result....
