93 f250 smoking white, searched lookin for help

[85stanky]

New to this forum but not new to forums so i know the drill, ive went through the faq's and searched around about my dilemma. Ive learned some stuff, cavitation and how to tell when you need certain new parts like injectors ip etc. I am trying to figure out where to start on this problem. I know i need to do a compressiong test, as it has 209k on the clock. Its a factory turbo engine, i just replaced a leaking line, the glow plugs and injectors are supposedly new. I might try and put a new install kit in just incase somethings clogged. Nowhere rents a comp tester, and theyre spendy im on a budget here kinda so. Anyway basically it starts up first try, runs kinda rough and smokes out unburnt fuel but white, i changed the oil right when i got it a few weeks ago. No coolant loss, its not trying to overflow or do any sign of cavitation. Filter could be changed out, trying to figure my best option and then order one. It runs clean once warmed up, especially when on the throttle. when you let off you can see a haze of white or blue smoke, especially going downhills off the throttle. Its not leaking oil or burning any as of yet, but ive only gone through like 1.5 tanks of fuel. i put some lucas oil injector cleaner into one tank so far, its a bit more responsive but hasnt really changed the smoke. hoping its not rings that went bad, any help would be appreciated. thanks jesse

So when you start it up and its smoking white, you smell it and it stings like unburnt fuel?

The fact it gets better when warm on that front probably means you just have some air intrusion somewhere even though it might not be leaving puddles on the ground, etc.

Seen it when I first got our truck. You might also find if it gets cold your same easy startup might become harder due to that.

Best thing we ever did on our truck is get a carrier electric fuel pump that a member on here sells. Totally changed the truck into an easy starter when cold and the pump was able to purge the air before startup and keep ahead of the small intrusion issues.

Let your truck sit overnight and unscrew the fuel filter the next day and see if its full of fuel.

WHite smoke is usually retarded IP timing. Has anyone been playing with the IP. If You can talk to the PO, ask about the age of the fuel system. @ 200K miles it's prolly time for IP/Injs

On the driver's side of the ip is a lever and piston called the advance piston. At idle push the piston in with a screwdriver. The truck should immediately run much worse and smoke like you are describing. My guess is that your advance piston is bad causing the smoke and when you push the piston in nothing will change.
If so you are in the market for a new ip.

any pictures of this creature? I would like to do this little test....I need an IP/injectors but it gives me the chance to play w/the truck and learn more about it

IP is center top of the motor. The advance piston is located on the lower drivers side of the pump. You can see it here:

Thanks, I knew where the IP was but had no clue about the plunger.

Yeah ive been thinking it was air intrusion, seeing as when im going down hill and i let off the gas pedal its sucking in air and will puff when i get back on the gas. I have replaced almost all of the injection return lines etc with a kit. I put some extreme kleen system cleaner that i got at a local deisel shop, once ive run a tank through i will be replacing the fuel filter with an IH one. I do need to replace some more of the o-rings on the injectors which could be sucking air if theyre old/worn. I will check the piston on the IP, i might be stepping up to a moose or DPS injector pump eventually also. But im looking for fuel economy here so im on the fence. Thank you all for the replies, hope to have this truck non smoking soon.

I just started the truck and checked the piston out. It is almost resting against the lever that pushes it down, im not sure if its supposed to be up like that. It didnt push down at all, like it is stuck. So im guessing the pump may be getting old. I believe its the stock one as the last owner didnt mention it being replaced, but he did say the injectors and glow plugs were recently replaced. Who knows though, i think ill be PM ing about the moose pump soon!

 

[icanfixall]

The moose pump in either of the types is a big plus to these engines. One just can't compare them to any other mods for these engines. I've had tow moose pumps and I that another... But this nest pump will be the baby moose...

 

[85stanky]

Nice its almost addicting! Ever since i got on this site ive been dreaming of all the things i would like to do! IP and injectors, larger downpipe to a straight pipe exhaust, gauges to monitor my engines vitals, intercooler. man its hard not to want it all

you have either bad valve seals or bad valve guides.
if it was air intrusion then it would start up and quit, or be hard to start up.

Run a quart of Power Service (or your favorite fuel additive) thru it with the next tank. It might free the advance.

Better yet, dump the diesel in the filter and fill it with Power Service or if you can find some Stanadyne use that. Warm up the engine first, then fill the filter, then run the engine at idle for three (3) minutes, not any longer and let set overnite. That puts the cleaner in the injectors and the IP.

are you sure about this? sounds like everyone else believes it to be the ip going out, which maybe it isnt air intrusion then and is just an ip going bad. maybe its just this piston not sure. it is possible, its got 209k on it and its most likely the stock heads so they could be staring to leak. anyway to test if they are bad? i dont have a diesel compression tester. im just trying and hoping not to spend too much as of now, im on a limited budget until i get some more side work.
