There's no oil separator on that engine. The valve cover is vented directly into the intake just in front of the turbo. I'd suspect that what is happening is that at sustained high speeds a lot of oil is being sucked out of the crankcase and into the intake. If that is the problem, you could retrofit a separator of some kind or just put in oil.
But, that's a lot of miles.
