Redneck what you are saying is really intriguing...
Can you help me understand how crankcase vacuum is correlated with the pressure/vacuum in the head / valve stem area? - is it the same? If that is negative, wouldn't that keep the oil from getting forced thru the valve stem seal (which is under pressure from the turbos half the time, and maybe not when off-throttle).
And how / where is the PCV system attached, and what impact it has on the pressures above?
Trying to understand how your fix works.
