Good idea to check the vent as stated above. There is an small oil seal in the fitting for the speedo gear. It is held in by a small round snap ring. A new seal (if still available) will prevent gear oil pumping up the speedo cable, provided that the fitting is not badly worn where the speedo gear shaft rides.
