6.0 turbo help

[craig4108]

Ok, so I have a 2004 with 4 inch turbo back exhaust, cold air intake, and I am running innovative diesels custom street tune. Yesterday it started smoking while I was driving. The smoke is a gray looking. The smoke gets worse when you hit the accelerator and it is really bad when you come to a stop. I kept driving and it started getting worse. It started making a noise kind of like a valve knocking and when I stopped it was really bad the truck wanted to die and you couldnt even see anything behind the truck. I made it home and parked it. Today I went out to take a look the back bumper is completely black and now it will not start. The motor will not even turn over. I thought it was a bad turbo but now I dont have a clue what it could be. Any help would be greatly appreciated.

Grayish blue smoke?

An injector could've came loose and dumped fuel on top of the cylinder hydro-locking it.

If it came loose while he was driving tho, the truck would've had a seizure(atleast it did in my case). I had hydro-lock and it was a pain. I agree with ajpu, check the injectors. You'll have to pop off the valve cover to see if there is excess fuel in there if the injector(s) have popped out

What's your oil look like? Fuel filter?

yes it's kind of a grayish blue smoke and my bumper is completely black from it. Oil is pretty black it was just changed 6000 miles ago and I am running amsoil in it. I haven't checked fuel filter but I changed it at the same time I did the oil change.

Not leakin any oil are you? Did you look under the truck after you tried to start it this morning?

[craig4108]

I looked under the hood this morning and did not see any oil leaks

Well take a look and see if you can see if any of the injector connectors came loose or popped off.

Pull your egr valve and clean it. It happened to me. Same thing. I actually replaced it but the next time I cleaned it

would I get codes if it was an injector, I am not getting any codes
