Blue Smoke
Hi all, I am starting this thread becuase it was getting intermixed with another. I am trying to resolve issues with my new rig. My 99 smokes. In short, the shop read 2 codes, bad turbo and #5 injector. I fixed the turbo, it was just a broken clip. Replaced the injector. It runs MUCH smoother, and smokes less (was like a smoke bomb went off), now it smokes a lot less. I have noticed at idle it smokes, some, but when I take off after idle, POOF, then it's not really noticeable when driving. But it still stinks, like rich maybe? What is my next step? I will change my oil. (someone sugguested). It's black, the previous owner heavily abused this rig. I also want to mention I only have 138k on this rig. Glow plugs were changed 1000k ago.

Report back after you change the oil. Things to watch after you change it are if you are burning any oil, and if so, how much in how many miles? You should also change your fuel and air filter so you can start fresh.
Any chip or tuner in your truck? How many seconds of cranking does it take to start your truck?

I'm going to change the oil this weekend. I already changed the fuel and air filter. Both were BLACK, the air filter was horid, gunky black.
As much as it has smoked, it's almost been 2000 miles since oil change, and no obvious oil usage.
All stock, no chips, tuners. It starts usually 2 or 3 cranks at most.

A quart of oil every 4000 miles or so ain't bad at all. In fact I believe ford says that oil consumption can be a lot worse than that, but I don't remember how much. With the air filter box, make sure it's not cracked and that the top fits good and secure. One of the bad things with the air filter box is that they are prone to leaking, letting dust get into the turbo and engine eventually destroying both, or at least shortening the life, if not caught in time.
I was just thinking, if that injector has been bad for a while, could you possibly have some raw fuel in the muffler causing it to smoke? Perhaps you need to get it warmed up and take it out and run it hard for a little while. It's a good idea to do that from time to time if you haven't done so recently.
Has the oil been changed the injector was changed? Might want to do that too.

I definately have driven it hard since the injector change. The air filter box is for sure not 100%, the typical clips are broken on front side so it does not seal it good. I was going to change over to the 6637 mod. The oil has not been changed since injector was replaced. Also, not sure if it's related, but the truck runs too cold as far as I am concerned, right at the first line above the C. I bought a new thermostat just in case that is the problem, have not put it in yet.

You may have just found your problem! A cold running diesel will not run right. It will always smell like it is rich from unburnt fuel, like when you first start it on a cold day. How cold is it where you're at?

Diesels need heat to run properly. Heat is what causes the engine to fire. If the engine is cold, there isn't enough heat generated to allow the fuel to burn completely. Using my trucks as an example, both smoke when first started on a cool or cold day. Once they warm up the smoke clears out. White smoke is what they both put out. If the thermostat is bad, not allowing the engine block to warm up like it's suppose to, unburnt fuel will be leaving the tail pipe in the form of white smoke. If the engine is warm and unburnt fuel is leaving through the exhaust pipe, it would be black.

I forgot that part. That is a sign of oil, and you said it isn't using any oil. But you did say that the fuel filter was black. Hopefully someone else will chime in on this. I believe it is possible for oil to get into the fuel system through the injectors if I'm not mistaken. Hopefully someone can help out on this.

Update. I just replaced my thermostat, wow, what a different, the truck got warm WAY faster and the needle was alot higher, just below center of gauge. I actually had to turn the heat down on my test drive.
Now I just need to resolve my smoke problem, although it appeared to smoke much less, in fact not at all by the time I got back from my drive.

Glad to hear that! When you changed the fuel filter you said the filter was black. Was the fuel in the housing black too? That might have fixed your problems, but I'd keep an eye out for other possibilities.
