Help 6.0 Blowing white sometimes bluish white smoke

Hi,

I am new to this Forum. I just bought a 05 F350 6.0L truck a month ago. It has 90,000 miles on it. When I test drove it, everything was fine. Shortly after I brought it home I noticed it was smoking.

Here is the weird thing. It only smokes when at idle or coming to stop sign, backing up to trailers. Seems like at low RPMs. It also doesn't do it all the time. One day it is fine and the next you can sometimes hardly see the truck (really embarrasing at stop signs). I am also getting like 10 mpg (that was pulling a couple of trailers and getting rpms up high to try and diagnose problems) The tail pipe smells like fuel not coolant. The smoke will just hang around too.

Now this truck has a Stage 1 turbo and the egr cooler has been replaced. The egr is dry. Has the latest flash from ford.

It also seems to blow coolant out of the recovery tank. It is not over full.

The coolant looks green too. I plan on flushing it all out, but I don't want to do anything until I know if I have to tear the hole thing down or what.

I am at a loss, and am getting really frustrated with this truck. Any ideas would be very much appreciated.

Thank you in advance.

Now I'm not that knowing of the workings of these trucks. When you say your degas bottle is puking coolant out? That was one of my signs of an egr cooler failure.

Even though your egr cooler has been replaced, if it's filled up with that green coolant it has an almost definite chance to fail again.

I would say pick up a scan gauge or a monitoring device to see how yours deltas of coolant temp and oil temp differ. Anything more then 10* would be a sign that it is failing.

-Flush that coolant out asap (DO IT YOURSELF) There are threads retaining the information on how to do so.

-Also invest in a egr delete kit if your local laws permit.

Puking coolant out of the degas bottle is usually one of two things. Either the head gaskets are failing, causing excessive pressure in the coolant system. The second and more likely thing is that the oil cooler is clogged, causing low coolant flow to the EGR cooler making the coolant that is in it boil and make excessive coolant pressure. This can be diagnosed by monitoring coolant temps vs oil temps with a scan tool. If it varies more then 15 degrees when driving about 60 mph unloaded then the oil cooler is plugged.

Do you have any way to check codes? The symptoms you describe sound like a stuck open EGR valve. It should log codes for something like this. I would pull the valve out and inspect it. Make sure that it is closed all the way and moves all the way through it's range of motion.

What scan gauge would you recommend? I really don't know that much about diesels.

On a side note, I was not getting much heat in the cab so I flushed out the heater core and now I am getting tons of heat (what it should be). A bunch of crap came out of there the way it looks.

After that I took it for a drive and it was blowing smoke non-stop.

The reason you weren't getting any heat is because your heater core was plugged, just like you oil cooler more then likely is. Sounds like your EGR cooler has now ruptured badly making it smoke. If you stop now and fix what's wrong with it you will probably be ok. Continuing to drive it will cause further engine damage and will probably blow the head gaskets, or worse.

OK.

So what would make it smoke before? Was it ruptured then?

Does anyone know if the EGR Delete is legal in Wisconsin? I'm thinking that is the way to go.

It was a bullet proof egr cooler in it now.

It was probably on it's way out and now sounds like it let go even worse.

Huh, well bullet proof has a lifetime warranty on them.....

I would delete it if you can. Not sure on the rules in wisconsin though.

I've had this truck in the shop. I monitored eot and ect and they where within 10 degrees of each other and I did the egr cooler on vehicle test. He is on his way to my house right now so I can do the headgasket test. The truck only smokes when you come to a stoplight and it's a blueish smoke that smells like fuel. Therefore I find it very hard to believe that the egr cooler is failing. Plus I have never heard of a bulletproof cooler failing.

When he got the truck the lip of the degas bottle was melted like someone had an extremely hot water hose resting on the edge of the neck. It was puking then, but after the degas was replaced by someone else he called me up and said that it was leaving puddles, I went and looked at it Tuesday night and couldn't find anything leaking, I told him to call me the next time it left a puddle and not move it so I could look at it. I spoke to him this morning and it hasn't leaked a drop since I looked at it.
