    Are you installing the seal the correct direction, and using the spacer washer? Only other way to leak into the case would be cracks in the case, or if your breather timing gear is not right I would say it could create enough vacuum in the lower end to pull oil past the seal HD started using plastic breather gears , they caused more problems IMO than they solved JMO
