Rear Main seal leak or something else?

I replaced it a couple of months ago with the tranny on and I couldn't offset the ends. With the tranny off I did offset the ends this go-around. With the lip toward the source, it will tighten down under pressure. Are they a seal that is different for a boosted engine?

After running the car a few miles, all is dry and happy. I guess the scratch on the crank was the culprit that was eating the seals. Thanks to all.
