    Its coming somewhere around compressor, but i cant find a source. Bottom of compressor is covered in oil. There is some oil on engine block, but i dont think its coming from engine
    And of course you cant see anything, because its so cramped. Anybody got an idea where it could be coming from?

    could be two things either oil compressor gasket or the other sometimes oil is coming from the rocker housing on top that gasket usually goes, parts are cheap labor is expensive it just takes a long time to get it done.

    Air compressor, power steering pump, fuel pump, or a cup plug. Too many options to start guessing.

    Had a minor leak as first described on a 2013.
    Not gotten worse, and I can barely see the oil.

    The outlet hose on the power steering reservoir is only clamped on, the connection loosens over time, and there was a leak, also cavitation sounds from the pump.

    Technician tightened the clamp, and reduced the leak and the sound.

    Should probably do this when the truck is warm from actually driving it.
