When 4x4 is engauged, there is transmission fluid being drawn into the engine via vaccum. Is this a vacuum actuator problem or another booger.
Do you

Could be the vacuum switch on the transfer case.Have any of the vacuum lines been moved or any work done on it? If the vent line is put on the engine it can do that.If nothing has been changed recently, it is most likely the vacuum switch on the transfer case.
