Oil leak

[briancox51]

Had my truck parked for about a week while hunting recently. When I went to drive it again, there was a small wet spot under it. Oil looked to have dripped from the area of the back of the motor. Kind of the back of the oil pan and front of the trans area. It wasn't all that much but I'd still like to take care of it. I'm not sure where it's coming from though. It looks to be coming from higher up. What's on the back/top there that could be leaking? High pressure oil pump or lines to it? Thanks for any thoughts...
