Well, I thought I’d go for the video. The engine decided to bleed out while running. I’m not yet even sure where it came from, but I had a significant puddle of oil, and about the time I noticed it, the engine stalled, and now the crankshaft has end play it didn’t have before.
I pulled the engine from the mount, mopped up most of the mess, and stowed it for the night. My vision is somewhat better early in the day, so I’ll pull it apart and see what happened if I can figure it out. Dammit.
