There are quite a few possibilities when the head gasket blows. In one scenario the exhaust gases will leak into the crankcase causing elevated pressure and the pressurized exhaust gas will take oil vapor out through the main bearing seals since the main bearing seals are not designed to operate under that kind of pressure.

The 3.8 GM V6 is prone to blown intake gaskets much more than blown head gaskets. The blown intake gasket causes a loss of coolant which in turn causes overheating and a blown head gasket. The problem exists with most 2000 to 2003 vehicles equipped with the 3.8 Liter V6. There were defects in the upper intake manifold gasket, throttle body nuts, and the throttle body gasket.
