Do you have a leak from your pressurized mags into the crankcase? If you've
got a leak here, it will pressurize the crankcase more and more as you climb.

Were all the "upper deck" pressure lines hooked up correctly?

Are you sure the oil is coming from the breather tube? You'd have a large
oil mess under the fuselage if you were losing oil that quickly. I would
be more inclined to think the oil is leaking from one of the turbo bearings,
and being burned in the engine or vaporized in the tailpipe.

Please keep us (me) informed, as I am considering a 231 for my next plane.
