Default 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.

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