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.

Thanks for the replies. I took it to the dealer yesterday and did lot of reading here as well. The dealer said Rear Main Seal is leaking and it is leaking around the oil pan (which is rusty and should be replaced). Total cost: $2138. Ouch!! I know of a pretty good mechanic and I am going to see what he will charge. After hearing that price, I did check the warranty and found about the 5 yr limit. I should have known but I thought it was 100k mile with no time limit. Oh well. I only have 58k miles on this truck.

I am going to look at the things mentioned here and what I was reading just to see what I find.

Thanks again.

It is almost NEVER the rear main seal leaking. Incompetent mechanics think it is, because a leak generated at the turbo pedestal will drain down the back of the bell housing and look like a rear main seal.

Trust me, it has been hashed out a thousand times on here, check your Turbo Pedestal O-Rings, and HPOP O-rings.

If it's the turbo pedestal, I have some good step-by-step instructions for you, PM me w/any questions.

Thanks. I have read a lot and I see lots of stuff about o-rings so I know what you are saying. I am not too inclined to fix it myself and I am not going to have the Ford dealer fix it. I'd guess replacing the o-rings is a LOT cheaper then the rear main??
