Is this a turbo or NA? A turbo has a breather line that goes from the oil separator to the air intake hose just before the turbo. This connection has a nipple on the intake hose which can get clogged, clean it out first.
If it is a NA, open up the PCV near the throttle body, throw away the screen, and clean the small diameter hose.

If the "smoking" goes away, that will keep you away from doing the entire oil breather box/lines for a long while.

Do not try to use Seafoam to clean the oil separator box, it will not work. If the box is clogged with dried oil, the passage from the box to the block needs to be cleaned out.
