Information:
I recently got a '95 Ford f-150 5.0 engine, Crew cab, Xlt, none 4x4. The guy i got it from paid 1,000 for it about a year ago it hasn't been driven much since then But, started on a regular basis. I seen some fluid under the truck about a week ago and checked everything nothing was low. So i drove it and continued checking the fluid daily, Soon i noticed oil was dropping pretty fast About a 1/4 a quart a day to 1/2 quart a day. Clearly that's a decently big problem. I'm not the most mechanically inclined guy with trucks/cars. I have basic knowledge such as I've changed oil, changed brake pads, spark plugs, etc. small easy tasks on vehicles. I did some research on line an from what i see i'm thinking its the oil pan, the oil pan gasket, or something in this area. Theres a couple of pictures below. One if part of the oil pan you can see alot of oil built up on everything in this area. Another is top-down view shows the oil on the grown an basic view of where its coming from. And other picture is simply the engine.

Questions:
I'm wondering what is leaking? If its possible to tell from these pictures if you need better pictures just tell me i'll go take some more. Is this something i can possibly do on my own? To avoid the cost of mechanic. I recently had a child 3 weeks old so cost is a big deal at this point but want the truck to be reliable as i drive it to an from work.

 

I couldn't get the pictures open maybe my computer but anyway try tightening the pan bolts. But that much oil check the rear main seal.

 

I also could not get the pictures to open . I did just do a oil pan gasket on my truck its a 94 f150 5.0 there is a write up on here on how to change the oil pan gasket also was very help full didn't take long . also I agree try and see if any bolts are loose.

 

I bet it's the front seal, you need to get under the truck, see behind the harmonic balancer, the rear main seal also leaks sometimes. Check both valve covers for oil (specially the rear corners). The pan is also a possibility, look all around that gasket. I could open the pictures opening the links in new tabs, but they weren't much help. Check also if your steering isn't leaking.

 

I got the pictures to open by right clicking the link and select "open in new tab"

Not enough detail to see where the oil is coming from.

I suggest wiping all bottom surfaces as clean as possible. With as fast as it is leaking, it shouldn't take too long to start to see the path of accumulation.

 

Power wash or degrease all areas that are oily. run engine with truck sitting don't drive while truck is running get underneath with a flashlight or trouble light do some looking .If its leaking that much you should see something .If not spray some cheap primer on suspect areas drive down road recheck.
