Until you get the engine apart... it's hard to say what happened, or what the extent of the damage is.

If the oil drive gear gave out... you wont' get an oil alarm, since the system is still full.

If the rod did break, or come off the crank... you are VERY lucky if there isn't a hole in the block.
