1997 2.2 L oil leak issue

My 1997 Camry with 2.2 L motor is leaking oil profusely beneath the passenger side of the engine. Over time it looses oil slowly however when the engine runs it really leaks. I've isolated about where it is coming from beneath the timing belt area as shown in picture http://imgur.com/1BDHbhx .

Any ideas as to what the problem is? All inputs are appreciated.

Thanks T-Rex

Assuming that the leak is not coming from of the top engine area and dripping down from either the valve cover gasket or cylinder head gasket, in that area the leak can be from the cam seal, crank seal, oil pump gasket, or oil pump seal. Since all these items are behind the timing belt area, repairing any leak in that area requires removal of the timing belt, so it is best to replace all those the seals while you are in there along with replacement of the timing belt and water pump, depending on the age of the water pump.
