If it was coming out of the tube at the front of the oil pan, that is usually a sign that it is injectors.
EDIT: There are also two other possibilities
1: PVC tube plugged and forcing pressure to build up in the oil pan "Not likely it would blow that much out at one time"
2: Hole in your piston, but you would also have a severe loss in power
