As I described in my build thread, last year, once I got the engine running, I noticed significant oil drops (or more) after each drive. With winter in full throttle, I decided to drop the motor, and see about fixing the leak.
Here's the view of the front. Maybe you can see some oil. Attached thumbnail(s)

Here's the cover off. No dramatic scoring. Also no gasket. I am trying to remember if I did this on purpose. Stupid #2?

No gasket, but it does appear some residue of a sealer. When she was running how was the oil pressure, cold and hot? What pump is this? As best as I recall, I used a thin skim of case sealer (Loctite 574). The pump is a 26mm Shaded, modified (from Aircooled.net). I only have a oil pressure warning light (something I plan to correct while the engine is out). All I can say is that the light went off quickly after both cold and hot starts, and never came on at idle. Attached thumbnail(s)
