Oil Leak Identification Help

[jastewart25]

i'm a total newbie when it comes to anything mechanical. i've read a few threads on identifying leaks but i could use your help!

will start tomorrow with cleaning the undercarriage as best i can as well as wiping valve covers down. i know not to wet the air filter and carb -anything else i shouldn't get wet?

here is what the floor looks like after truck has been driven and parked for a few hours. each time i move it, the oil drips in multiple places.

any thoughts? thanks!
