Hello All, Sorry about my lack of input, working too much. heres a link i found, im still having this issue with oil consumption and blue smoke. Definitely a vac leak, measuring 25 inches vac with a vac gauge at the back of the intake manifold and at the vac pump tee cap. High cold start idle drops down too fast, slight shake, double the normal oil consumption, gotta be a broken or cracked vac tube or disconnected fitting. Keep researching. thoughts/ideas? Please let me know. I have full turbo on both side, almost 0.8 Bar (with Agency Power Diverter valves), normal vac at pump should be 17-20 inches.

Hi I saw your post about the CTT oil smoking issue. I am having the exact same problem. My T hose broke in the back of the motor and after I fixed it, I am still having tons of smoke. I had some questions about what happened to your fix of if you did anything else. Any help would be greatly appreciated.

Do you still have the CTT? If so, how is the car?
