Could one of you guys post a photo (not a drawing) of the turbo to intake manifold connection on a OM617?

The drawing in my Haynes manual is not very useful. My intake has a cast-in step about 260ish degrees around the inside opening. The outlet of the turbo fits loosely in that opening. If it went all of the way around I'd think an O-ring would seal the turbo to the intake but it looks like said O-ring would just blow thru on the part without the step.

I wonder if I'm missing a part or if there's a different seal other than the O-ring that I have, which seems to be the right diameter. The turbo seemed to be leaking when I got the car so I'm thinking it was wrong from the start. No telling WHAT the PO did to it!
