ok I dont think I was clear enough, the leak is at the side if the head where the line screws into what i thought was the injector, it has a keeper bolt at the bottom and the part thats leaking has a nut about 3/4 wrench size, is this the injector in the side of the head or is it under the valve cover? i thought this was the injector since the line from the pump scews onto it, ifit is the injector we tried turning the socket on it but it felt like it was connected to something else, so we didnt force it not wanting to damage another line if there was one connected to this area up in the head.bottom line is do we have to take off the valve covers to get to the injectors or is that it on the side of the head? Thanks
That's an adapter mounted in the head. It has an inner injector line connected inside the head. if you are leaking oil there, replace the o-ring. If fuel is leaking, the inner line is either loose or cracked. Somtimes when you loosen either inner or outer, the older adapters will spin inside the keeper. The newer have a solid adapter to prevent this.
Pull the valve covers to hold the inner line while loosening. A 7/8 wrench on the inner line...3/4 on the outside.
You will have to pull the covers to do any of this...unless the outer line(s) are cracked or leaking. If it has a Jake, it'll have to come off too. No big deal.
