    From the looks of the last pic it looks like the belt is slinging the oil so I am betting it is the timing cover.

    Typically oil would not actually be on the belt. It is normally slung from the air moving around from the fan or the pulley's and rotation of the belt. Something leaking near a point of rotation mass normally causes the buildup like I see in that pick.

    That makes sense. I don’t see any leaks/residue from the timing cover. It looks pristine

    take it somewhere where a real mechanic can look it over you've seem to have come to a dead end with your own oil mystery source

    It may come to that. Changed the filter. Wiped down the frame and hoses that had oil. Lots of oil in skid plate and lower control arm, that’s where the majority went when I spilled oil. Took the skid plate off this time and wiped everything down

    I think you've answered ur own question to where the oil came from, if u check the dipstick and its at full level the mystery is over

    Dipstick was at full level. I’m hoping it’s just residue from the earlier spill that I didn’t clean up as well as I should have in aug

    Put a piece of fresh cardboard under the truck to see if it’s still leaking. It’s been 2.5 hours and no drips

    Haha I mentioned that I had spilt some oil in my original post. Probably A half quart along the frame etc. Gave it a quick wipe at the time, not the full clean up like I should have. I gave it a good wipe down today

    I only skimmed the thread...
    OP, is the CV Boot intact and dry? Also, check to be sure the steering rack dry.

    Place a paper towel below the oil filter drain hole.
    Other wise it could take a good while before enough oil leaks to finally make it to the ground.
    Hopefully you got it taken care of.:thumbsup:

    I haven't read that you checked the ATF level. ATF is red but starts to turn brown past 50K or so as it accumulates contaminants - that's one reason we should be flushing ATF every 80K or so. ATF lines along the driver side chassis rail and to the radiator.

    Clean as a whistle. The dot on the cardboard is black paint not oil. Not a single drop in 18 hours

    The first step in finding a leak on industrial machinery is to determine the type of fluid, general overall inspection and the a thorough overall cleaning to remove all traces of the fluid.

    Wind and crazy angles in a tightly packed engine compartment make it all the more difficult

    One option I didn't see mentioned was a leaking oil pressure sensor, but who knows until you thoroughly clean it and trace it back to the source it's all conjecture
