Cotter pin in oil pan?

It sounds like the rear seal is not sealing properly. May need to drive it a little to see if it is a continuing problem. It the engine is not vented properly it can build up internal pressure and contribute to oil leakage.

Thats been suggested by two others, so I think I'll try that first. Get some running hours on it and see if that seats it. Since it was only run a short time before it was dropped in (like minutes) one suggestion was that it might not have swelled enough with oil and isn't sealing. It might have been over-filled too as it doesn't currently have a filter on it.
