1969 Ford 4000 white smoke diesel

Justinscott33 · Apr 29, 2022

Ive got a Ford 4000 it white smokes like crazy. Im thinking its not
burning all the fuel or something. As Im driving it to the field the
smoke starts to burn my eyes. Is it injectors? Fuel lines? Valve?
Need help its a 3 cyl diesel thanks in advance fellas

Unburned fuel.

Could be the pump, an injector, or a dead cylinder.

I am no diesel person but I cannot see it being a dead cylinder. If a dead cylinder you should be feeling a big miss and low power. At least that is the way I would have felt with the two 3 cylinder 4000 that I had but they were gas. I still cannot see a dead cylinder without a jerk every timer that cylinder should be firing. A 4 cylinder you would not be able to tell a dead cylinder as easy.

How would I go about checking pump or injectors. If I pull injector would I need to try and prime the system back

The easiest and least expensive initial shot at a solution is to buy 2 16 oz. cans of Sea Foam liquid and put one in the fuel tank and the other in the crankcase....with the oil. Hook a good plow to it and go out for a couple of hours and make it struggle, getting it up to temp and maybe even pushing it on over to the red line.

Take it back to the shop and drain and refill with fresh oil and a new filter. Refill with fresh diesel. Turn it back on and see if your problem has disappeared. If not, then start worrying about what to fix.

I have a '65 3000 that I did an inframe engine OH back in mid 80's. Last half of last year it started to have a lot of white smoke on startup and when I would goose it in N, would get black smoke. I did what I just told you and you can't see the exhaust, even on startup....well maybe just a minute or two of white on a cool day.

Thank you Texas Ill give that a try this weekend

White smoke can be either compression or timing. I'd start with pulling the injectors and do a cylinder compression test to see what shape the engine is in. Low compression will cause lots of white smoke until engine gets hot. White smoke means pump/injectors are getting fuel to cylinder, but there's not enough compression heat to burn fuel correctly.

You can crack loose the line at each injector with it idling, one at a time, like pulling a plug wire.

Listen for it to change the sound of the engine, or not. That will narrow down which cylinder, if any are misfiring.

Doing so will not get air in the system.

Also, is the engine coming up to temperature? Thermostat in and working?

If you are using ether to start it in cold weather and it knocks and pings it might have a broke ring or 2. And if it is just idled around the yard doing putter work all the time it is not getting worked enough. Take it out and work the off it for a couple days and it will probably clean up. Our loader will get that way not as bad as you describe but same thing. I use it to load hay with it about wide open throttle and it goes away till it gets idled a lot again mostly by dad using it.
