The most common places for oil to leak from the front of that engine are 1. Valve cover, 2. crankshaft seal 3. distributor seal , 4 camshaft seals and last but not least the head gasket. Head gasket and valve cover is easy to see if you look from underneath the car. Camshafts will leak inside the camcover and run down front of engine and drip out next to crankshaft in most cases. Distributor seal will be visible if you look down from front on passenger side of engine. All are easier to find than to fix.
