White smoke when my truck is cold

Hi i was wondering if white smoke is normal on a 2006 6.0 f-250 mainley when it is cold when i take off i can see white smoke comming out of my exhaust it seams to clear up when the truck warms up. What would cause this EGR? head gaskets? somthing else. I have had the EGR replaced and turbo under warranty about 18k ago maby andy ideas. Thanks

White smoke most of the time means antifreeze when it is cold park it with the nose down hill pull the EGR valve and if it is damp round 2 EGR cooler, did they change the oil cooler when they did the EGR have to do both at the same time. Do you have gauges need to know the difference in EOT-ECT that is a must to know where you are over 15 degrees running 55-60 down the freeway you are in trouble
Let me know what you come up with.

EOT=engine oil temp ECT = engine coolant temp

have you tried smelling the white smoke ? does it smell like coolant or fuel?

how cold is it outside when you start it ? and how warm is the engine before it begins to clear up? any rough idle at all while this is happening ?

'04 6.0, 4.5" lift, straight piped, SCT tunes by Innovative Diesel, studded, coolant filter, EGR delete Tru track in the rear, sounds by JL audio some other odds and ends

Ok no nog ECT or EOT guage as of now but i am getting a ECT EOT and fuel pressure guage soon have not been able to smell the exhaust i see it in my review it does it anytime my truck cools down overnight or all day does not seem to matter what outside temp is but does seem to be a little worse when it is colder out like it is know in the 50's but i seams to all clear up as the truck comes up to temp

This is from another PSD forum someone that know a lot about the 6.0 you can that this statement to the bank

--------------------------------------------------------------------------------

Here is the deal with the 6.0. Any good tuner (person writing your tunes) is not going to give you a tune that is going to tear up your truck. There are trucks all over the place running 400-420 rwhp with 750-800 rwtq all day long without problems.

Yes the 6.0 is known to blow head gaskets. This is why it happens. The Ford Gold coolant contains silicates. The silicates are not able to handle high EGT's generated by a good load or relatively high boost when run through the EGR cooler. They break down into a jell like sludge and fall out of suspension. This crud gets caught up in the tiny coolant passageways of the oil cooler. As the cooler clogs up it restricts coolant flow to the egr cooler. Now the egr cooler doesn't have enough coolant to carry off the heat generated by high EGT's. The limited amount of coolant in the egr cooler flash boils causing high pressure in the cooling system and the truck pukes coolant from the degas bottle due to the pressure. (it has to go somewhere)
Your uninformed Powerstroke owner is not monitoring his coolant temps and oil temps so he doesn't know whats going on and he keeps driving it this way. The problem get worse, the pressure causes the egr cooler to rupture. Now the egr cooler is leaking coolant into the intake manifold which then runs into the cylinders. Again the high combustion temps cause the coolant to vaporize. This causes unacceptably high cylinder pressure, the TTY head bolts stretch due to the additional pressure and there go your head gaskets.

Ok now you know the problem. Here's the cure. Get a good engine monitoring solution like the Edge Insight so that you can monitor your ECT and EOT. If those temps get more than 15* apart at normal cruising when at normal operating temperature your oil cooler is clogging up. Rebuild it now to prevent all that down stream damage from occurring. Flush that Ford Gold coolant crap out of your engine with a couple bottles of Restore. This is made specifically to clean out that silicate residue. Now refill it with a silicate free Cat EC-1 rated ELC coolant. This removes the silicates that clog the oil cooler from the equation. If you live in an area where you don't have smog inspections delete the egr system. If you can't delete it replace the egr cooler with the cooler manufactured by Bulletproof Diesel. This is vastly superior to the Ford oem egr cooler and it will not fail on you. If you find that you need to replace head gaskets replace the TTY head bolts with ARP studs and use black onyx (Victor Reinz) head gaskets. If you have to replace the egr cooler always replace the oil cooler. That is the source of the problem.

Now that you have addressed the common problems that scare the hell out of people, get an SCT tuner (i like the X3) and install some custom tunes and drive the heck out of it. DO NOT baby it. The Powerstroke hates this and will rebel with turbo issues.

Turbo issues are also common repair points with the 6.0. People like to complain that it's because the VGT turbos are pieces of junk. This is not so. The VGT vanes in the turbo need to be exercised regularly. This means making them go through there full range of motion. So put your foot in it regularly and let is see some full boost runs. That will keep your VGT vanes from getting all sooted up and freezing up because of the soot. Again, that is what happens when you baby it. Put you foot in it and you will have less problems. Lay out of it and try to milk it for mileage like you would a gasser and you're going to have turbo issues. Don't let it sit either. That is also the kiss of death to the turbo. The unison ring rusts up and again you have turbo problems. So now that you know you need to give your turbo a regular work out to keep it happy, give it a proper cool down as well. Just whipping into your parking place and shutting it down will lead to coking the bearings and again major turbo issues. Running a good synthetic oil will help here immensely because it handles heat so much better and resists coking. But always let your turbo have time to cool down. This is one of the reasons you need a Pyrometer (EGT gauge), Let the EGT come down to 350* before shutting your truck off. This only takes a couple of minutes, especially if you take it easy on it for the last couple minutes of your trip. If this is too much hassle for you get a turbo timer that will automatically delay shutdown when you turn off the key to allow the turbo to cool down.

Injectors. Fords injection system HEUI fires the injectors with High Pressure Oil, to the tune of 4,000psi at Wide Open Throttle. Maintenance is critical here so you can not let your oil maintenance slide like you can on a gasser. It will kill your injectors. The injectors also are known to suffer from something that we call stiction. That is when the oil side spool valve of the injects hangs up or sticks when cold until the truck warms up. I believe this is caused by varnish buildup that is common to dino oils, especially those containing paraffin. Using a good synthetic oil will take care of that because it actually cleans the engine as it lubricates. If you do find yourself with some injector stiction add a couple of bottles of Rev-X to your oil. It has cleared up 99.9% of the trucks it has been used on. 2 bottles run around $70. A new injector is about $250-$290. Be anal about keeping your oil clean and fresh and changing your fuel filters regularly. The other thing that kills injectors is low fuel pressure. The fuel pressure needs to stay above 45psi at all times and is typically set around 52 psi from the factory. Well the Factory fuel pressure regulator spring is weak and looses it's tension over time and can't maintain adequate fuel pressure. There is an updated rebuild kit that uses a better, stronger spring. Installing this spring will bring your fuel pressure up to about 62 psi and solve that. Get a fuel pressure gauge. It's important.

So that covers the frequent complaints with the 6.0. They are all well known at this point as are the solutions. Does it suck we have to fix Ford's blunders? Heck yes it does. But again we know how and once done you will have a very reliable robust truck that is well worth the effort. So address the issues as you can and enjoy your truck. It is a dynamite vehicle. I love mine.

Can't explain away Ford's logic. International uses Fleetrite ELC. Think about it. Whats is another silicate? Sand immediately come to mind. What is sand? It's an abrasive. Besides that it turns to a gell from the heat as it goes through the egr cooler trying to carry off the heat from high egt's resulting in the sludge that clogs the oil cooler. There is a substanial body of evidence supporting this.

Not having silicates is a positive thing. It has no adverse affects. ELC coolant is good for 300k miles without any additives and extendable to 600k with an additive pack at 300k. The new Delo ELC is good for 750k miles or 8 years extendable to 1 million miles.

I think it pretty much speaks for itself.

I'm on a campaign man. That Gold crap is killing our trucks and people need to know. It is the cause of the biggest problems we have with the 6.0 and the bad reputation the 6.0 has. And it is pretty cheap and easy to eliminate. People should know this. So yeah, I'm beating that drum. The other drum is the need to monitor ECT and EOT before you blow your egr cooler and head gaskets.

I just did a flush with Fleetrite Restore, VC9, lots of flushing, installed a coolant filter, and switched to ELC. Im curious to see what my coolant filter will look like after the first 500 miles, I know there is still most likely some crap in there still as I still have the stock EGR and oil cooler at 34k miles but I doubt there will be anywhere the abount that we see out of most of the posts with opened up coolant filters.

I recently installed the DieselSite.com coolant filter kit on my 2006 6.0. The kit came complete with everything you need and also came with the new billet aluminum filter head, looks really sharp.

PGreenSVT, dude you need to change your screen name to "ELC FOR LIFE!"

2 Stroker, Do you seem to think it is when the injectors are cold?? This was the only thing I had in mind before and after reading your post it seems that could be it.

I dont know my truck is doing the same thing but it's like 20 degrees out and after like 3 or 5 minutes its all cleared up I smelled the exhaust just smelt like diesel I think its just moisture in the exhaust pipe from the frost just evaporating out of the system ive been watching coolant level and its been staying the same. heck there was so much of a cloud this morning I couldnt see most of the side of the truck. Gotta admit I though the truck looked cool with lights on wraped in a smoke cloud out in the pitch black hour of 6am.
