Narrowed it down to valve stem seals. Doing leak down and compression test dry and wet now, to make sure.

The smoke is white, smells like oil(it is oil), smokes as soon as the car warms up, on and off boost, and on and off load.

ya you can do a quick leak down yourself if you have access to compressed air. just tdc one cylinder and pump some air into it. if you hear air leaking from the oil cap removed.. its your rings.. if u hear from exh tips its ur exh valve seals, if you hear from intake its ur intake vavle seals, if you see bubbles from the coolant tank its ur head gasket...this is what i did when i dont have a leak down tester and only with a compression test hose fitting.

Great info, thank you. I will update this thread when the shop tells me the definite diagnosis. What was your problem?
