My 95 4x4 all of a sudden dumped all the oil out of the bottom of the engine and I can't seem to find why or where it came out of. It's not the filter or plug. So where else could it be coming out of. It took about 1/2 a mile to dump all of the oil.

 

Sound like an oil cooler line may have broken. They run from the drivers side of engine block to the oil filter adapter. There is also a pair of oil lines that go from the oil filter adapter to the radiator.
