good morning my name is ***** ***** I will assist

with the mileage you have, it may be as simple as the seal. in a lot of cases, the surface it rides on does get scored but can be easily fixed with a speedy sleeve with the new seal. in other cases, the rear main bearing may also be worn causing the crank to wobble and the seal will leak new or old. in that case new bearings will be required.

at any rate, it will need to be pulled apart and then the determination can be made as to the cause
