I asked my friendly mechanic to replace the oil seal but he said the work is too much for him to handle. He recommended a stop-leak additive he once used on their tow truck and also recommended to his customers. He suggested that I might try it as opposed to spending hundreds of dollars to hire someone to replace the seal. So...I put in an 8 oz. bottle of "AT-205" from atp professional auto parts. Will let you know the results in a couple of weeks.
