I seems like everytime I bare down on the throttle to merge into traffic gray smoke rolls out of the tailpipe. Not full throttle tire smoking stuff, just accelertion with authority. It also seems like the engine is starting to use a little oil. Stock engine with 11K. Any ideas?

 

sometimes under hard throttle you will see smoke come out of the pipe, this is usually unburnt fuel, i dont think there is too much to worry about, all deisels smoke under hard acc.

 

A little smoke I would expect, but this is a cloud. This seems to be excessive and getting worse. When the turbo starts to kick in is when it starts. Could bad turbo seals cause it or maybe the crankcase breather?

 

Black smoke:
Caused by excessive fuel for the amount of air drawn into the cylinders. Some black smoke on hard accel or at higher altitudes is normal.
Excessive black smoke could result from restricted intake or exhaust, inoperative leaking or weak turbo, intake hose(s) leaks, leaking or worn injectors, fuel return or supply restriction, stuck Exhaust backPressure Regulator valve or solenoid. Also PCM inputs such as BARO MAP ICP or EBP sensors. you might want to check the air and fuel filter as well.
