    Has anyone experienced the fuel pump leaking fuel in oil? The Mechanic said it's prabably injectors but the guy who rebuilt my injectors said it's unlikely it could be leaking that much, since it seems be almost a gallon an hour so I'm leaning towards fuel pump. 2010 transtar

    Id default to the injectors. The only way i can think for fuel to be put into the oil is through the injectors either leaking or putting fuel into the cylinder at an improper time. was it an international dealer who rebuilt the injectors?

    Dump a small bottle of uv leak dye into the fuel filter bowl and then run the engine with the rocker cover off for about 30 mins and watch with a uv light to see if there is trace of dye up there. With that much of a level change it will be easy to see if an injector is bad or not.

    Its either clean up a little bit of oil or start throwing parts at it until you hit the right one.

    I’m curious to know, with that much fuel leaking out, do you have any fuel rail pressure fault codes?
