I think the leak is actually from the gasket behind the adapter plate in which the oil seal is pressed. I used a turnbuckle from the rear engine lifting point to a beam which the PO had glassed intop the cockpit floor.
More awkward than difficult. Especially the two bolts holding the plate which mounts the voltage regulator and the two relays - I may relocate that. I may also remove the oil pressure sender and the oil alarm sender to a remote location if I can find a hose. I would really like to rewire witha key instead of the fuel pressure switch but I am too busy.
Hope to finda seal at the bearing shop tomorrow.
The Oil seal no is : INA 40277
