Leaking turbo?
I believe the KKK on the SDL is leaking, there is no shaft play (side to side or front to back) but after the vehicles idles for about 5min or so and I go step on the pedal... a plume of white colored smoke blows out the backside.
Obviously it's not loading up with fuel. Oil consumption is minimal too. Does this sound like what the deal is with the car?

If you have minimal oil consumption, I would tend to think it was fuel and the smoke might be caused by the low combustion temps from idling for 5 minutes. Does it tend to clear up right away?

Yup, clears right up. Maybe my ALDA is still too high.

How much oil is there in the intake crossover pipe? Is there oil in the turbine feed pipe? Is there oil in the flange ahead of the compressor?
To dismiss blowby, vent the valve cover breather to atmosphere and cap the turbo intake pipe. Does the same smoking occur? Sixto

Little in the crossover tube. Just like a flim in the tube from the turbocharger to the x-over tube. There is some just before the turbocharger, but I associate that with some blowby.
I'll cap that plug tomorrow and give it a spin.
