Is there a definitive fix to the CX-7 smoking?

[AboveAverageJoe]

I purchased a 2008 CX-7 that smokes intermittently. I've searched the internet read the threads on the turbo motors smoking. I've learned about the OCC, modified banjo bolts and the PCV fix from Mazda. Is there a fix out there that really works? The more I read, the more confused I become.

Thank You,
