The sensor connected to the oil pan itself is the oil level sensor. Its connected to the low oil light on your dash.

The one you speak of above the oil filter sounds like the oil pressure sensor. Its located either here or behind the intake on the rear of the block.

It should look like a black cylinder that screws into a fitting.

Is there still something in the "port" of the block? If so I would thread a screw inside to try and back it out. If that seems impossible you could always plug it and use the "port" located on the back of the block.

Here is the oil pressure sensor located on the back of the block.

The hex head pipe fitting in this pic should be in the port your talking about.

Do any of these things look familiar?

You might try an EZout or you might try to drill it out.
If you can get a dremel with a 90 degree attachment you could drill with a small drill bit and then go a little bigger and then a little bigger until all the old one is out, if you are careful you might be able to save the threads as well.
