i have been troubleshooting some oil smoke on startup with the FD for a while now. the problem is the exhaust would smoke oil, but only if i started it completely cold -like after it had sat for 5-6+ hours.
i replaced the turbos with low mileage great condition ones, got the oil injector lines replaced (both were broken, good thing i'd been premixing) and still had the problem.
well, i decided to check into the oil injectors since i've heard they can sometimes go bad and leak when they sit over night. i tested both of mine (which i should have done before, when i replaced the broken lines, but oh well) and it ended up that the rear oil injector was bad per the test in the FSM. the front oil injector checked out fine... i believe the rear oil injector slowly leaked oil into the rear housing when it had long enough to sit and seep.

this job is a total pain in the *** and requires the removal of the UIM (obviously), the primary and secondary fuel rails, the solenoid rack and a few other things i'm forgetting. not fun!

anyways, i'll report back after i start the car up, after it has sat for a whole night.

Dissect the bad injector with a dremel when you are done and show us pics of it's root cause failure.

thanks
