My 04' 911 turbo smokes when it first starts and I have recently had to add a quart of oil Any thoughts Thanks?

This may be related to issues with your air oil separator or AOS. Many Porsches share a similar design for this part and while it might not be faulty, it may be less efficient now than when it was new. Some newer model Porsches have added a MotorSport version of the AOS, after purchase, to alleviate this problem.
