If you have no access to a lift, jack the passenger side up, take off the wheel, remove the wheel well cover, and you can see almost the entire front of the engine (meaning the crank side). And no, the engine does not have to be pulled out. The only time that you need to pull the motor out of a B13 and B14 (91-99 Sentra) is when you are replacing the entire engine.
Back to your problem, I suspect it is the front main seal.
