that might help you diagnose your spark plugs. how long after start up does it take for the smoke to appear? any external leaks? (puddles on ground)

RETed will become famous soon enough
Okay, let's assume it's the turbo (turbine piston ring) that's bad...

Try and do a high idle test?
Shift trans into neutral...
Rev up to 4kRPM's for at least 10 seconds.
Do you see smoke out the exhaust?
Do you see a LOT of smoke out the exhaust or a little?

Does it smoke more when you go into boost?
