Replace the sending unit. Approx. $30 at parts store. I just replace one in my 1992 Wrangler. Requires a special socket ($12.)

you can also use teflon tape and wrap the threads.

Rarely do the leak around the threads, replace it before it creates bigger problems.

The oil pressure sending unit could be bad. Or the oil pressure gauge could be bad, but normally gauges don't fail............I would have someone check out the oil pressure sending unit.

Depending on mileage--could just be a sign of engine wear Remove oil sending unit and replace with mechanical gauge to determine actual pressure
