The pics below are related to injector #3.
The oil deflector hold down machine screw screwed it self out, jumped out of the deflector, and managed to avoid the gaping holes in the head.
I could only use feel to search for the screw, searched twice without finding it, concluded it was it the pan, but searched one more time and found it laying on the head.
That socket head machine screw has a very narrow clamping surface. And it is trying to clamp aluminum. I am not surprised it came loose.
With the screw gone, the deflector stayed almost in place, but shifted enough to rub on the wiring. The pic shows a large worn area on the glow plug wire and a small worn area on the injector wire. Apparently the deflector would occasionally make momentary contact with the injector wire, which I assume would cause the PCM to shut down that injector supply circuit until it was rebooted.
I think I need to do something different with the deflector hold down screws. I have 271 Locktite. Properly cleaning the female threads would be difficult. I am going to see if I can get some flange head, or at least steel washers to widen the clamping surface on the aluminum.
