I'm new to the Powerstroke engines (as far as fixing on them anyhow)..
I'll try to explain it as it was to me.. Simply.. LOL.. (and to those that know much more than I do, I'm sure I'm not precisely correct)
The injectors are basically a "common rail", although, the fuel rail itself is cast into the head. They don't have individual lines to them. The fuel is delivered to the injectors around 50psi.
The injectors are told that it's their turn by the truck's computer.
The part I'm not totally clear on is the high pressure oil system.. To my understanding it works like this: It has a high pressure pump that delivers oil to the injectors, and oil works similar to a hydraulic system.. The high pressure oil pushes a piston in the injector, which then pressurizes the fuel further, and pops the injector off.
I believe the fuel is between the lower and middle o-ring, and the oil is between the upper and middle o-ring.
From everything I seem to read, usually instead of pushing fuel into the oil, it will push oil into the fuel and burn it. However, I was told it could be possible to get fuel past the o-rings and into the oil.. But, after seeing the shape of the one injector, the bad lower o-ring, and missing copper washer, I suppose it is possible it is "dumping" fuel into that cylinder and in turn, allowing the fuel to get past the rings.

Some of my fondest memories of these visits are those of learning to drive a tractor at the helm of Uncle Cecil�s 1948 Farmall Super A. Uncle Cecil was the second owner of this wonderful little tractor, but it was almost as though he had adopted an infant. The original owner was a man from Minnesota who bought her from a local dea
