1990 Buick Century 6 cyl Front Wheel Drive Automatic

I have changed the oil pan gasket and the front crankshaft oil seal but the car is still leaking the oil on the passenger side of the motor. I cant seem to find where it is leaking from. Can you help?

Is it to the front of the vehicle or back by the fire wall. Have you checked the Valve Cover Gaskets.

Also check the Oil Pressure Switch....
