Ford 5000 white smokes

HI you all.been pulling my hair out on this one.
1967 5000 ford diesel 233 engine and simms inline pump.this engine was overhauled 100hrs
ago. .030 over bore new pistons, head redone
and the injectors redone.On first start up at temps under 80 or above the engine will blow
white smoke out the exhaust and misfire for 5 min.then will run fine all day.At first I set the timeing at 19 btd.and it will hardy run at all.
reset to 25 btd and it helped. Then up to 30 btd but
the engine semed to clater alot under load.so I moved it back to 25 btd.The tractor did this before I overhauled the engine but I just figerd
it was wore out because it had lots of blowby and used a lot of oil and was low on power.
Now there is no blowby and dont use oil and has
a lot more power but still white smokes bad at
cold start.Could the pump have a problem? Iam
afraid its not going to start at low temps.

Here is a pic of the 3000 helping us put the 5000
back together tractors helping tractors.

Maybe I'm not understanding this but lots of diesels smoke white smoke until they warm up and then they run fine

I dont know about that motor,hopefully somebody that does will answer.Old diesels smoked quite a bit.I ran a 961 Ford and it would smoke white smoke until it warmed up,but it was worn out.I have worked on motors that were like that.It takes a diesel a while to warm up.They kind of like to be a little hot,especially if they arent broke in yet.If it smokes that way after its warmed up good I would think its getting water in a cylinder somewhere.If its only white smoke when its cold it might be over fueling.Like I say I am not an expert on a 5000 Ford motor.I have worked on diesel motors that did that,and some times it could be fixed,sometimes it couldnt.Old type motor maybe did that,but it kind of sounds like its over fueling,motors if they are non turbo,non aftercooler,non air to air,smoke more than newer ones,if not that it might be seeping a little water in a cylinder while its cold.The way to tell that is take your finger,touch the inside of the exhaust pipe,touch your tongue,if it tastes sweet its antifreeze and not supposed to be in the exhaust pipe.Dont do that a lot because it doesnt leave your body and if you accumulate about a cup full of antifreeze you might die!Another way is the cylinder leaking water will be lots cleaner than the ones that arent,so if you pull the exhaust manifold,and look at the head,if one of the exhaust ports is clean and the rest are carbon covered you know where the leak is.Other ways are,black trails of carbon running down the outside of the muffler,pressure building up in the radiator,boiling antifreeze out of the radiator,water in the oil.If it sets a couple of days,loosen the drain plug on the oil pan,oil will float on water if its sets long enough,by loosening the plug if there is water in the oil,the water will go to the bottom of the pan and come out as water before the oil if the drain is lower than rest of the pan.While changing the timing helped it you think,Diesels now days have variable timing made into them to get better fuel mileage.Old ones like that are probably set to where they are supposed to work best under all conditions.Where you think it might be better now,if it gets real cold it might not start,or it might get hot if you work it hard,I dont know.Since changing the timing helps are you sure its timed right?It would have to be close or it wouldnt run maybe.Just giving you things to think about,I could be wrong.

Thats true but this seams to be alot of smoke.
And I will add that the misfire is gone when
you load the engine like in road gear but when the govener leavels off the engine it comes
back in till its warm.I normaly let my tractors
warm up before I work them but this is extreme.

Since you say that it sounds like an injector is not right somehow.If I remember right a Ford diesel is like a Caterpiller,Ive worked on a Cat and it was the injectors causing white smoke like that.I could be wrong,but thats what it took to fix a 3208 Cat doing that,new injectors,or nozzles,tips,anyway what fogged the fuel was wore out and it smoked white smoke.Since it misses,that could be another reason for the smoke,it doesnt take but a little dirt to mess somthing up in the fuel lines,or pump,or nozzle,even a little water when you fire a diesel up can mess up an injector,so even if you had them cleaned,and a few drops of water got through the filter,it could have messed up a tip on an injector,or a little bit of dirt in a line,or rust might do it too.

the diesel pump shop that rebuilt the injectors
said thay was poping at 500psi before thay rebuilt them.My ford book has them poping at
1500psi.when the pump shop told me that
I figred the pump would not open them
after the injector rebuild.

I think your white smoke is caused by unburnt fuel , did you change the pump setting at each degree setting 19,25,30. if you didn't there is no wonder it is pigrooting.its fueling and firing are not synchronized.
Find out the degrees of timing, I understand the FSM is a 5000 in USA and fires at 21 degrees but don't take that as true.
Bring the No 1 cylinder to TDC [top dead centre] on compression stroke [you may have to remove the rocker cover to observe the valves] the flywheel tdc mark should correspond with the pointer on housing, move the flywheel back to 21 deg. The timing mark on the fuel injection pump drive coupling flange should then be exactly aligned with the mark on pointer attached to pump, adjustment can be made by loosening the cap screws on coupling.
If you want to check take pipe off no 1 at pump and turn motor by hand, pump should spurt at the degrees btdc.
This applies to a FSM so the principle would be the same with your motor.

I rebuilt a 4500 Ind. Ford last year and I went with the overbore instead of sleeves and my engine done the same as yours. Poor starting, white smoke and skip til warm, I had the inj. pump and injectors done, I chased the timing all over the place same as your doing. Finally I checked the compression and found it extremely marginal.

Old mechanic much wiser than I said it would be fine after a good break in, so the owner comes picks it up and I have not heard from it since. Often wonder how it done tho.

npuller,

The opening pressure on the 5000 injector is 2750 PSI. This and a breakin should clear up your white smoke.

I think I'd get it on a plow or something heavy and work it hard for a day or two. Break it in. If that doesn't cure it, I'd suggest pulling the injectors and doing a compression check, and if that doesn't turn up anything I'd send the injectors BACK to whoever did them and have them done again.
Doubt it's a pump problem provided it's got decent transfer pressure and good filters.

White smoke clearing off when warm is a sign of low compression with those engines, or a bad injector.

Were the valve seats replaced or were the valves and seats just ground during the overhaul?
If the valves are sunk in too far it won't have good compression. Just an idea. Jim

Hi Rod.The tractor has been worked for 100hrs
some plowing and some round baling.Was working
very hard on the round baler had to turn the
belt pressure down because of fire out the exaust.So I figred it was broke in by now.
what sould the compression be at?

Good advise from all, white smoke is unburned fuel normally, if injectors are worn out and overdoing it might cause the white smoke, or bad compression, have that checked. If rings are not seated/or installed incorrectly or valves/guides were not done right could be a possibility. My small diesel smokes on started for a couple seconds, then clear. On some injector pumps there is an adjustment for flow and it could be turned up too high. Get a service manual and check out compression specs and adjustments. If that is an aftermarket pump, could be suspect. My 2cents

One more cause of white smoke that sounds like a good possiblity is air pumped through the high pressure injection circuit. Sometimes a small leak is hard to find and can let air be sucked into the circuit. Also a restriction like a partly clogged filter or fuel line could be the cause.

Without checking the compression spec I'm going to say 4-450 cranking at a good clip.

Fire out the stack?? Think I'd check the valves again just for the heck of it, and then pull the injectors. .015 on the intake and .018 on the exhaust when they're warm. Probably OK, but doesn't hurt to check...
'Fire' would suggest a lot of unburnt fuel going up the pipe.
Even one I've got cranked up here doesn't show fire in the pipe, but they will all occassionally blow some carbon out, and that has a pretty good glow about it (sparks).

Rod it was fire, yelloish red about 6in long and
the rain cap was starting to glow on the tip.the pump was turned up some.Today I needed to rake
some hay.The temp was 56 and the tractor had not
been run sinse monday.It started and smoked bad.
I stop it and turned down the pump restarted it
and it may have help some.Ran good raking hay.
but thats not much of a load.Well start it tomorow and see what happens.
