I know my motor is tired and my turbo is tired. I'm sure my motor smokes a little bit when I had it NA. My compression is good on all 4. I'm not sure, what the problem is. When I hit an exit ramp sometimes it will smoke like horribly sometimes it wont smoke that bad.

What could be the problem? When i blew my rings I had constant smoke... so i donno about this.

if ur ---- is high mileage i bet ur piston to cylinder clearance is excessive

 

oil return line completely flat? going downhill could make oil flow back up a little, causing the turbo to smoke.

 

could be a headgasket or valveseals, both were bad on my high mileage z6

 

are you tuned? Maybe your running rich

 

maybe the seals are bad on the turbo?

 

what color smoke is it and whats the temp like... it might just be cold condesation smoke..
