Is the sheet metal baffle inside the crankcase under the road draft tube hole in place? It sounds like the oil in the pan is flowing forward on a hard stop and getting sucked up into the PCV system. You might try removing the draft tube and welding a big washer into the bottom of it, leaving a smaller hole for the PCV to draw its vapors through. There's no need for the PCV to have a hole over an inch in diameter to pull its air through.
