I saw your post about the transmission oil getting into the engine oil on a D7G. The only way that can happen is for the shaft seal on the transmission pump to be leaking. It is located on the upper, right, front side of the flywheel housing. The bearings in the accessory drive that power the pump are lubed by the engine, and if the shaft seal on the pump is leaking it will quickly fill the engine with transmission oil, just like you are describing.
Sorry for the delay in posting, but I needed to find my service manual just to make sure before I commented. Hope this helps.
