I presume you are referring to the positive crankcase ventilation?

Sure you can re-route the pipe into a bottle, but then your engine is violating emission regulations in just about every state and country in the world.

Why not fit a Raco CCV4500 crankcase ventilation filter (or similar) and stay inside the law?

If your engine is in good nick, the oil content in the ventilated air should not be not that much, IAC. Maybe that high boost turbo is effecting your engine?

Don't ascribe to malice anything that can be adequately explained as stupidity!
