You need to clean the engine and then run the vehicle while watching the area. The most common failure is the oil sending unit located near the oil filter. I have also seen a leak develop between the oil pump housing, which is mounted directly behind the hamonic balencer and the engine block.

My car is leaking oil. i dont know if its the oil pan or the oil filter came loose? need to know where the oil filters located.

if it leaves small spots the chances are its the pan gasket but the oil filter should be located up in front of the engine on the right hand side... depending on the size of motor

Has a bad oil leak coming from under the car . The only time it leaks is when the car is running, was told that it could be the oil pan gasket or the oil sending unit, what I wanted to know is where the...

The oil pressure sending unit screws into the engine block so you will need to look between the oil pan and the head.I suggest that you try tightening your oil filter first.

1993 chev. cavalier RS convt. has oil leak somewhere

this being a side mounted 3.1 liter (v6) the front of the engine would be on the right side of the car from the driver's perspective. if the oil is coming from that side cocentrate your pinpointin there, make sure it is not one of the valve cover gaskets and oil is running down from the top (common) and making pinpoiinting the leak difficult because it tends to spreak on its way down. Seals tand to leak more when the engine is running, so you may have to run it while parked for a little while and check for the leak. It may be the crankshaft seal if it is localized to below the crankshaft; Or if it is coming out of the timing cover then it may be the camshaft seal of the lower intake seal. Intake seal leakes are next to valve cover gasket leak the most common on those engine. Update us. Good luck.
