2004 Chrysler Sebring

Engine Mechanical problem
2004 Chrysler Sebring 4 cyl Front Wheel Drive Automatic 79,000 miles

I have a 2004 chrysler sebring 2.4L and at first I was noticing that I was having a small leak under my engine and I located it where the oil pressure sensor was located. I have removed and changed the sensor, but it seems that it still leaks. I check it by feeling under the sensor and there is where it still leaks.
On the sensor the threads stop and there is a space about 1/8 to the housing of sensor. Should it be tighted flush all the way to the engine block or should there be small space in between the sensor and the engine block.
Any help to resolving this leakage and to stop the drops I am starting to be annoyed of on driveway.
