After taking a drive in my Series V there is a steady oil drip coming from the drain hole in the bottom of the bell housing that bolts the gearbox to the rear of the engine. It stops dripping after a few minutes with the car parked and leaves a 4" round oil spot under the car. I'm thinking this is the result of a gearbox front seal leak. Anyone with similar experience and suggestions on how to confirm without removing the gearbox? Other than the embarrassment of leaving oil stains wherever I go, is this a repair I can delay? I'm not anxious to tackle a gearbox removal in the near future.
