An oil seal rides against a rotating shaft to keep lubricating oil in the housing and dirt, water, and grit out, holding the film a bearing or gear needs while sealing the point where the shaft passes through the case. The sealing lip runs on the shaft surface and is the part that does the work of holding the film.

Seals harden, crack, and lose lip tension with heat and age, and a weeping shaft or oil found below a housing is the sign the seal has failed and is letting lubricant past. Match the seal's inner diameter, outer diameter, and width to the seal coming out, since an oil seal is sized to both the shaft it rides on and the bore it presses into.
