Exhaust Smell, compared to!!!

I'm a newbie with diesels and am experiencing some issues...at least I think I am.

I've been doing alot of reading to hopefully educate myself.
Alot of the reading right now has been about "smoke color" and different exhaust odors. Also egr and injector issues.

I'm going to try and take this step by step so that when I explain my issue I can provide as much pertinent information as possible.

Anyway I hope someone can tell me what I might be able to compare specific exhaust smells to.

I think I may smell unburnt diesel...but I most definitly would be guessing.

Also whether I'm actually seeing white smoke or a light blue color..........I'm kinda on the fence.

I will say this.......it was about +20C when I filled my tank a couple of days ago. It went to -3c last night. Blowing tons of smoke "water in fuel " light came on - truck stalled.

Going to drain hfcm (on frame rail) and add some anti-gel additive to the fuel. I have a hunch this isn't going to SOLVE the problem.

I have some other issues but hope to get my smell and color test sorted first.

PS. Some A** tried to jack my wheels last night...busted up my ignition switch. Good thing I could get it towed and a new tumbler installed. The door handle will have to wait. Maybe the foker put water or piss in my tank!!!!


Huge thanks in advance for any help.

HHMM, I wanted to say it smelt kind of sour.....but I'm not sure if that's actually right. I'm going to do the drain right now. I'll start it up and take a good conciencious whiff.

I'll post my sniff test within 1/2 hour.

Thanks for the quick reply.

Well I just noticed a sticker.....Motor is a 2003 model.

OK I drained some fuel from HFCM plug (frame rail) and I must say.....It looks pretty clean....definitely has no visual imparments by what I can tell. Yellowish color fuel.

HUGE billows of white (with light bluish tinge) smoke at start up..lasted 4-5 minutes before lessening...also billow at take off from a start and heavy acceleration in park.

I would say that it smells SWEET!

I'm going to let it warm up for about 15 minutes then whip around for 10 or 15 minutes. See if the "water in fuel" light reappears or if power loss or stalling reoccurs.

Something just does not seem right since 2 days ago when I last drove it.

I'm shaking in my boots.

well if it smells sweet thats most likely antifreeze.

unburned diesel is a white smoke but i think it stinks. blue is oil.

but yellowish fuel? thats weird. have you replaced the egr cooler yet? and does it run likes theres nuthin wrong or its definitely showing something?

Once it warms up it runs good (not great). It does slighty hesitate sometimes.

Runs pretty rough when it first starts and if I don't let it warm up enough (15-20 minutes) it really hesitates during acceleration.

I have not changed the egr! It seems more popular to do the delete, opposed to repairing the cooler.

I'm thinking....whether this is or isn't the issue it would be benificail to delete anyway.

I'm just worried that if I drive it right now I may cause further damage or problems. It's a long weekend here, so I have no recourse until Tuesday.

first off it sounds to me like you need to get this truck to a shop that can pull the codes for you , and it also sounds like you need to get the latest recalibration from ford , should fix the cold start issue , if it runs alot better warm then may have a hesitation, that could be egr valve problem, if coolant level is full , then i dont think you have a egr cooler goin bad , not yet anyway , get codes and get iot reprogrammed , and let us know how it does from there
