I'm having the same deal, about 1/4 cup of oil under the truck every morning, seems to be more oil on the outside of the pan then inside. Going to pressure wash the sht out of the bottom tomorrow with some Dawn detergent and try to pinpoint where it's coming from. guy i bought the truck off of (about a week ago) said his father in law (probably in his 70's) just put new oil in and thinking he didn't drain any previous oil. some oil on top of the engine finally burnt off after a few hours of driving. new to this site and will be uploading quite a few pics to show my problems, not to smart in engine mechanics either but that's why i pay for internet.
