N14 Celect Plus Misfire and Gray Smoke

I think I found the C mark, with it lined up both 3 and 4 are loose with four on the end of exhaust/start of intake. Tried setting the injectors on both and again, its bottoming out on the lock nut and not the injector. I really dont know what I'm doing wrong.

 

I finally got it set, the marks are definelty gone on my accecsory drive or it was replaced with an aftermarket unit without them. I'm about to fire it up and see how it sounds. The manual I have says to set the injector with the valves but that sets the injectors at the top of the stroke so they bottom out mid-engine rotation. The injectors should be set at the bottom if their stroke and not top, ditto.

 

Well, the misfire is still there and not much better, the smoke is still eyeburningly full of diesel. I'm going to pull the injector harness off and put it on the other truck, my logic being that if the miss travels to the other truck ita for sure the harness and if it doesn't it's for sure valvetrain related.

 

None, the only one I had was on the Kenworth dash with ECU Power Low, charged the batteries and it went away. The engine diagnostic switch lights up the stop engine and check engine lights but they don't flash or turn off, and starting the engine just makes them go away. Got me scratching my head.

 

Found this video on youtube of what is basically my exact problem, but this looks like an STC model N14.
Basically exactly what it sounds and looks like with an exhaust manifold and muffler, the missing and popping isn't as prominent at higher RPMs though.

 

Changed the oil and the filters and it only smoked a small cloud on start up. The misfire looks like it's in two cylinders, 3 and 4, would you guys recommend swapping 1 and 3 and see if the misfire follows as a diagnosis? Also found out the switch I thought was for checking codes only tests the lights and doesn't pull flash codes. It also wont go over 1500 rpm in neutral but still no check engine.
