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.

Yes, if the oil pressure sending unit is bad the oil light may come on.

Find out why it is on. The oil light being on may indicate low oil pressure. It may be nothing more than a bad oil pressure sending unit, but it may be more serious. You need to know why it is on. Check your oil level, and if it is full, I would look at the oil pressure sending unit and see if it is connected or leaking. If all looks good seek professional help.
