    I replaced all injector o- rings and was still getting fuel in oil. Put dye in filter and detected a leak on #1, replaced injector with new one and it continued. Went back and put 2 titles of dye and tried detecting the leak under cover with no success. I changed fuel pump thinking it might be that because no detection was made under valve cover with no success. It continues to put fuel in oil, any ideas? thanks

    Same as I told you before. It's not coming from anywhere else.

    I am goi g to try checking with air, is there a reason the dye would not have been detected?

    Did you use a black light? I've sometimes had trouble finding dye, but air pressure is easy enough.

    We always remove valve cover and jakes and feed fuel to the injectors through the supply port with a pressurized tank we made. Same tank we use to bleed DD15 etc after filter changes. Look and listen for any fuel coming out of the injector solenoids. Usually it is easy to find.
