Have an 06 6.0 leaking oil from the bottom front of the motor. Can't seem to find the source. The valley and everything else up top is dry. Seems to be coming from the center of the front of the motor a little closer to the drivers side of the block. One of the lower pulleys seems to be soaked the most, the one that has a few rubber lines and one hard line going to it (not sure what this is) but none of the lines show signs of leaking.. whats in the general area that are common oil leaks on these things? any help would be appreciated. If I can't figure it out unfortunately it's going to be a trip to the stealer this week...

unfortunately I cant figure out how to edit the above and or the computer wont cooperate. I was able to find a leak on fuel pressure regulator that's attached to the under hood fuel filter. I replaced the bad seals along with the "blue spring update" and stopped that leak (whole kit was $50 from Napa). Hopefully that's what the source was. Truck does idle a bit smoother and has a little better response. (could just be my mind playing tricks at this point but who knows...) beer time...
