oil leak coming from where??

I have an oil leak I just found. It looks like dirty oil. I do not believe it is trans fluid. It is leaking down from between the engine and transmission as far as I can tell. There is a cover that extends down right in front of the transmission oil pan and I believe behind the transfer case. The oil is coming through what appears to be a hole in this cover(?) and also from its edge. I call it a cover because that is what it looks like. It does not look like it should be sealed. So I think the oil is dripping down and accumulating on top of this cover and then leaking out. My trans fluid appears to be full. I did not check the oil as I just realized it might be engine oil. I was originally thinking transfer case oil which it still could be.

So any ideas what could be leaking in this area? Any idea what it will cost to have it fixed? Would this be covered under the engine warranty? Is there a way to check the level of the transfer case oil?

Thanks so much and sorry for the poor description. I did the best I could.

Here is a picture of where my HPOP O rings were leaking. They are located on top, next to the fuel filter. Get up on top of your truck, with a flashlight and if the truck is running it will be a gusher, if it is not, it will be hard to spot.

JUST A FYI, I needed 2 gallons of oil, I think a 5/8 wrench, a #47 torx at a 90 degree angle (or a straight one with a wrench to twist it b/c it becomes oily and slippery) some paper (makeshift funnel to fill HPOP res), strong battery charger, allen wrench(s), a good memory lol since you have to take apart some fuel lines so that you can crank on the Hpop fitting (lots of little springs and plastic pieces, ALOT of papertowels, and small container to pour the oil into the HPOP. Total install was like 1.5 hours but after reviewing the info, I didn't replace ONE of the O rings, but it wasn't leaking so like JimTJr said, if it ain't broke don't fix it. After you do this install, letting the fuel pump run its course (to fill the fuel filter since you d/c it and drained it) and crankin' it a few times it started!

lol it feels good to do it. ALSO FYI, there will be oil/diesel in the valley since you had the lines off... spray degreaser and blow out with water, it will ''leak'' oil for a little while, but in reality its just the excess running out of the valley down the back of the engine block and tansmission. You can tell that its just water if you get up under it though.

also a 12"+ needlenose does wonders precisely picking up small springs (inside all fittings) and the HPOP cap from the valley of the motor. They are so small, slippery, in tight, and of course 'springy' so you're likely to lose them if your not very careful.

The O-rings on the HPOP fittings are actually #6 O-ring boss. The ports in the head are #5. You can get them at any hydraulic shop for pennies.
