Hi,
Without being there to confirm, I would be most likely to think it is either the oil pan or the front crankshaft seal.
If you look at the two attached pics I attached, pic 1 shows the crankshaft pulley which is the lowest point the belt runs from and the second pic is the oil pan looking straight up from under the engine.
First, behind the crankshaft pulley is where the seal is located. See if you can tell if it is wet in that area. If it isn't, then check around the edge of the oil pan.
Let me know what you find.
Joe
