It seems like something that holds oil pressure is leaking, and is allowing pressurized oil to spray out.
In my experience, the most common cause is the oil filter or oil filter gasket. Sometimes, plugs for oil passages have leaked too, or an oil pressure sender switch. Since I do not know the Neon engine well, I cannot say for sure which would be at fault.
You might need to get this thing up on a mechanics hoist to find it.
