HELP!!-Oil Leak......

Hey everyone. Thought I'd bring this thread back to life.
My 340 has a small oil leak as well on the oil filter side, far to the back.
The transmission housing is gooped up from the leak, but only on the filter side of the engine. It's dry as a bone on the other side. I haven't been under the car yet, but would you say it's probably the filter adapter?
