I recently noticed that I have some oil leaking out around the bottom of my engine. I cant really figure out where its coming from. Thought I might let yall take a look before I haul her to the dealer. Its not enough to drip but its on both sides of the frame. Should I be concerned, or what? Let me know what yall think.

BTW, only look at the frame rail. It was raining that day and that water looks like oil in the pic.

Use some engine degreaser on it to clean it up and let it run to see where the leak is coming from. Thats what i had to do to find a leak on a 1070, just follow the wet area to the highest point.

Most oil leaks are minor issues. Mostly a seal to be replaced. Unless its the crank seal, then this should not be a problem. The engine degreaser should be used and then followed by an internal oil sealant with a fluroscent dye in it. These are sold at any major parts store.
If there are leaks, then the dye will leak out and you will be able to see the exact locations of the leaks. The dye comes with a sealant, so there is a possibility of after using this in the engine for a week, all the oil leaks are gone.

I had a hard time telling what type of leak that is, could it be diesel fuel?

put a piece of newsprint or cardboard under her and narrow it down.. then you can also 'smell' the oil droplets to determine if engine, hyds, gear or fuel.

Minor oil leaks like shown are nearly impossible to find and dealers usually tell you to go away untill it is at least dripping. Try degreasing it very good and see if they come back. It could have been just the gaskets weeping a few drops and now may not be leaking at all. It could also be caused by spilled fuel. I would clean it up and evaluate the extent a lot closer before hauling it back to the dealer.

If it has a crank breather hose on it you can get a lil fluid from them too now and then.

This is very good advise - in really tough leaks (to find) I would take some flour & spray it on the underside of the motor after dreasing it. I found it real easy to see the 'path' of the leak then. When I worked on car engines it was, unfortunately, not such an uncommon occurance :(
