Wow - newly rebuilt BMC engine doing some crazy things...

Hi all. Thanks in advance for your help. I'm well versed in Porsche and BMW engines, having written a few books on them, but this early English stuff is giving me fits! BMC B-Series engine, tuned by Janspeed, installed in a 1969 Adams Probe 16 (one of three made - Kubrick used a Probe 16 in the Clockwork Orange - truly a unique and unusual car). Anyways, the engine was rebuilt, and I've been having issues with it. I'm going back and forth with the rebuilder, but I thought I would post here for some input.

I can add more later, but the crux is - after mucking with it for hours, I finally got it running well enough to take it on a drive through SoCal. After about 20 miles or so, I parked it in a lot, and noticed it was *dumping* oil out the bottom of the engine. Not where the shift cables go, but near where the bellhousing meets the engine/transmission. It's a bit hard to explain, I will post some photos.

At the same time, there was some type of smoke coming from the hole where the starter disconnect is located. It did not smell like clutch smoke, or burned oil - it pretty much had almost no odor whatsoever. It did not smell like coolant. Very, very odd. Very, very odd. I have video and I have photos. I also have no clue where the oil came from. I removed the engine, and took it back to the shop, and they put a scope down there and said it looked dry. Wow, nearly impossible. They also ran it on the bench in the dyno room and it was bone dry. I saw it running myself. I'm completely flabbergasted, as this engine was an environmental disaster site when I brought it home.

They suggested that it was pouring out of the shift cables, but I highly doubt that - it doesn't appear that way on the video. Frankly, I do feel silly, as I would have paid much more attention and took many more photos if I thought that the problem would just magically disappear. I thought it was a main seal popping out (I was sure of this), but that wouldn't just seal itself. Everyone here (including the folks at the shop) are confused.

Thoughts?
