Leaking Injectors

There seems to be alot of diesel around the injectors while trying to start the truck. It is an extremely hard start it seems. I cannot seem to figure out the leak or where to begin to trouble shoot. Everything is torqued per procedure.

Images are at night since daylight savings. Will try this weekend to get better photos.

I cannot see much of anything with the pictures. I would start with the line nut, the return and then the injector nut.

Yeah going to try and re install them. Basically everything is wet around the injector areas.

Return lines have given me issues in the past.

Usually the taper on either the line or the injector will have some crud in them not allowing them to seal. Take the lines off and give everything a real good clean. They can become damaged and not seal no matter how clean it is though. I've also seen where the return line won't seal properly. In that instance, the injectors were rotating slightly due to the slop in the anti-rotation slot in the head. So the face would be at a slight angle to the return line, and with the banjo bolts being so small and torque so low, it wouldn't bend the return line enough for the faces to seal. Had to put a wrench on the flats on the top of the injector and hold it counter-clockwise while I tightened down the hold down nut.

sounds like the sealing washers under the nozzles. could be the feed leaking also, but youd need to leak a lot of fuel to make it start hard.

If you have upgraded the injectors, and have used bodies on new nozzles, the seal at the intermediate disc can weep fuel.
If thats the case, all you can do is have the bodies turned flat or try some anaerobic sealant on the threads of the nozzle retainer. Weston recommended some CAT sealant for this, I have not tried it. If anyone has a cheap source for that sealant please let me know!
