2008 f250 6.4 Will NOT stop smoking !!!! please help :(

i recently bought a 2008 f250 6.4 about 2 months ago. love the truck ran great no problems at all . Although the last 2 days the truck just keeps blowing majorrrrr grayish smoke out of the exhaust. id say about every 10 min the " cleaning exhaust " notification pops up then the smoke starts. today it came on 5 times so far. Also i have noticed when i give it more throttle i hear a loud sucking noise that comes and goes and engine makes totally different noise . fuel milage went from 13.5 to 10.0 . Took it to ford and they said nothing is wrong with it. just a normal thing with diesels. funny because this never happened before, charged me $ 237 for ABSOLUTLYYYY nothing !.. I'm a new ford owner so still trying to learn as much as i can about these diesels. PLEASE can anyone help me ???????? I'm lost .

This doesn't sound 100% normal for diesels. I am having similair problems. And it can get bad quickly. Mine started doing the white/gray smoke a few days ago, started throwing EGR valve codes, and eventually the DPF started showing codes.

I am assuming, and maybe I am very wrong, that this could be an EGR cooler leak. Sounds like maybe some coolant is getting mixed into the intake from that or another source.

Is this occurring any less frequently when the engine is completely warmed up, or is it just as bad when its warm?

I am hoping someone else chimes in on this, but I would get that EGR cooler checked out right away.

Is this happening after driving like a steady speed on the highway? Also is this after it just rained or while it was raining?

thanks for your input . when its running at cooler temperature it does not seem to do it . but as it gets warmer then it all starts happining . the truck did do this about a week after buying it but went away that same day. didn't really pay much mind to it. but the past few days it has gotten extreamly bad. just bombes the roads with soooo much smoke, and gas milage just keeps on dropping. i just don't understand why ford would tell me this is totally normal. i hope i don't do more damage if i keep driving it .

EGR cooler leaks aren't that common on the 6.4 but thermostats are common. If either (2 in 1 housing) is stuck open, the engine doesn't get hot enough to burn off the DPF. The temp gauge may show normal.

This will give you smoke once the DPF starts plugging up.

However, EGR valve issues do exist and you can count on replacing the housing as well since the 2 don't separate well. Don't assume the EGR cooler is leaking if you see moisture in the intake, it usually comes from the EGR valve itself if it still has the coolant lines attached.

I too am having the same issue. Mine is more common when I'm driving in colder climate. It has happened when its raining as well. My Ford Dealer hasn't been able to make it happen while they have it. It can go weeks without smoking and then it will just start again. Strong smell in the cab when it starts smoking. Any help is appreciated..

If its not smoking regularly, it's not thermostats. Is it happening more before an oil change? Check your oil level. If it is high - as in an inch high or more, you could have an internal fuel leak at an injector (usually the jumper line). This will cause you to suck the mixed fuel and oil into the intake and burn it that way, causing smoke

I change the oil every 5K and the level doesn't change between changes. At least not yet. Ford does the service work and I check the oil every time I buy fuel. I had the fuel filter changed when I bought it and then again 10K miles later. It was clean as a pin. I have new turbos, high pressure fuel pump and charged air cooler. About to put a match to it next!!!

Good advice, Thanks for that. I guess I need to look into the Thermostat when I do the EGR delete. I am not having a problem with temperatures at all myself, and it isnt a regen problem (I used to have regens without hitches maybe twice per oil change), but the last 4 months or so they have been much more frequent, and now the EGR valve issues. I could see how the EGR cooling lines could be causing the leak in.

Any way for me to check the EGR cooler to check that for leaks before I tear it off? I want to ensure I am troubleshooting this correctly myself.

Sorry if I am hijacking.

Best way is to remove the EGR housing that way you can look at the intake and the outlet of the vertical cooler.
