Advancing the timing
Howdy,
If I am standing in front of the truck which way do I turn the injection pump to advance it? (counter clockwise or clockwise)
I was pulling 8000 pounds up a long somewhat steep hill and I didn't see any black smoke at all. I should see a little shouldn't I?
Thanks,
Gr8ride

To advance the timing turn the injection pump toward the passenger side of the truck, or counter clockwise as viewed from the front. In my experience, which is limited, the lack of black smoke is probably more related to the fuel volume than injection timing. That is adjusted through a small window on the passenger side of the pump with an allen wrench. Clockwise increases fuel volume and counter clockwise decreases it. I would go in 1/8 or 1/4 turn increments and try it. Be careful. Too much fuel and black smoke and the temperature will increase when you pull hard. I saw a detailed post of how to set the fuel volume on here somewhere. I believe you have to put a mark on the harmonic balancer in the 1:00 or 1:30 position to have the allen screw accessible. Good luck!

If you wan't more fuel turn your screw in one flat of the allen head screw, 1 and a half if you like to fog mosquitos, any more is just throwing fuel out the tailpipe. lgspitler is right on the timing, it has nothing to do with smoke, he's also right on the direction to turn the pump to advance it. If your truck has a healthy diesel sounding "crack" to it I would't worry about the timing.

If you do play with the timing the Ford spec is +or- .030 for the timing mark on the pump and housing it mounts to so we are talking very small adjustments. A slight timing advance may improve throttle response and as Fordhog said make the injectors rattle a little louder.

Howdy,
Now that I know adjusting the timing isn't going to do what I want, I think I will hold off on increasing the fuel until I get a pyro like banshee suggested.
What brand pyro gauge do you guys recommend?
Thanks for the info guys.

what if you are seeing constant white smoke and to smell it it smells like fuel
would this be the injector timing or the fuel adjustment on the side?
it is a 94 7.3 idi turbo
thanks

If the engine is at operating temp the white smoke is oil from somewhere. Sounds like a turbo oil seal to me...or some other seal or ring broke or hole in the piston or... If it is not up to operatine temp then you have glow plug problems with the after glow untill the engine warms up.

Go navy,
In the exhaust manifold is the best place, in my opinion, close to the place making the heat so you get a good, early reading of what is coming out of the cylinders. Then keep that down to about 1150....1200 tops

I'd try to find out which cylinder(s) is(are) the problem by cracking loose the injectors while it's smoking and see if you can at least make the smoke go away. If you find one, pull it out and see if the tip is bad. They should have a small point in the middle. If you just see a small hole, the tip is gone. That would let it get un atomized fuel, which won't burn. If it looks ok, get it pop tested anyway, maybe the problem's inside. There's my 2 cents.
