a lot of smoke in boost, sometimes?
 

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
