MJ: I agree it 'looks like' fuel dripping but I think it was just very hot oil.

Patxipt: The tube extends down quite a distance, about 1" from the end of the exhaust outlet.

*Edit: Officially official: I just measured it. 1/2" from the bottom of the exhaust pipe outlet.



I am beginning to wonder if a straight tube in the flow of gases blasting by it actually creates a suction on the tube?

BTW, how does the angled cut on the end of the tube create more suction?

I understand how a true venturi tube works, but this setup could never be a true venturi even if I made the tube into a true venturi shape because it is closed at one end.

I have not run the engine again. Maybe later today.

One other thing, this 2nd version collector ring sounds a lot different than the first. I have no understanding why. I am guessing maybe the straight down 6 o'clock exhaust outlet versus the curved rearward 8 o'clock outlet.
