Good job! I would have done the same repair if I were in your situation. Sometimes people are way too quick to jump to replacing the pan. The Teflon tape idea probably would have worked as well after you chased the threads. Usually the pan will strip again after chasing out cross threads (you can usually tell by how loose or wobbly the plug is halfway in), but the tape idea is interesting and could take up the extra space. As to the crankcase pressure, there shouldn't be any in either direction (pressure or vacuum) as that's a sign of a failed pcv valve. Too much pressure in the case will blow seals out, Audi 2.0t longitudinal has the issue of flipping the crank seal around when the pcv fails and you get a nice leak out of the bell housing
