05 Montana SV6 Oil on Oil Pan

Those engines have a huge problem with oil leaks. Bout everyone I look at has a leak to some degree. Sometimes the oil filter leaks, oil pressure switch, Intake manifold end seals, valve cover gaskets, oil life monitor sensor or all the above.

The most common area is the timing cover gasket, cover crank seal and the oil pan gasket.

I would check the oil filter first as the wind created driving down the road will blow oil everywhere.
