Has anyone ever used an oil scavenge pump on the oil return line from their turbo?

From what I can make out, the smokey problem I had on the dyno and shortly after, was due to a blocked, or partially blocked, PCV system.

While this shouldn't be a fix for a partially blocked PCV system, it seems like a good idea to help keep the oil flowing out of the turbo.

And it would seem you can get them pretty cheap - under $200

Thoughts/experiences?
