@lucasg.03 Take off the stator cover and see if you can see a dribble of goop coming from the seal behind the flywheel (also possibly a good time to get a flywheel puller if you don't already have one, I think Yambits sell one). Once you take off the flywheel and stator you can replace the seal in situ as long as you're careful not to mark the sealing surface of the crankshaft.
