Hey Guys
Just finished getting my single turbo set up complete so i am officially welcoming myself to this section of the forum

I do have a problem though....
when i go into full boost (14lbs) the car lets out quite a bit of blue smoke during deceleration.. the car is using quite a bit of oil because of this...5-10 lbs of boost there is virtually no smoke
i am pretty convinced that the oil is burning/leaking from the turbo... but am not totally ruling out an engine problem....althought that is freshly rebuilt aswell....
i am running a .70 (70 thousands/inch) oil feed restrictor and a -10 return line....
thx in advance for any help
