Thanks Cheezit,

Yhe smoke looks to be a blueish/grey smoke. The truck has been sitting, but the veins arent stuck, I know what thats like. I am going to drive it to a boat show tomarrow, its all highway, so If it doenst clear up by the time I get back I will call the dealer and have it back there. I wonder if maybe I have a injector leaking or an injector o-ring leaking casuing the smoke at a light. Like I said its not all the time, only when warmed up it seems.

I started it, let it run for a minuite at the dealer and pulled away no smoke, got about 10 miles down the road, stopped at a light, and it smoked.

A pull of balck smoke, a idle or under hard accel, I can go for that but not this smoke. I dont have a cat. but will that make this much of a difference.

The truck doesnt run poorly, run rough, or have poor fuel mileage, also no CEL either. This ones got me stumped.

If you need the vin to see exactly whats been done PM me and I will get it to you.

so far as an injector o-ring goes. when they fail one of to things tends to happen they either hydorlock the cyclinder or fill the crankcase with fuel. check you oil level.
my guess is going to be an injector(s) either under or over fuel for short periods of time. with out the truck and a scan tool hard to tell.

 

Ill try to expain some of it.
we have a report that all dealer in a group are judged by. if the number are to high we get in trouble and ford comes in and does an audit. So if a dealer can limit its high doolar claims then they will. If a different dealer down the road is on the low end of the list and has some room to play they will take the money.

As a tech Ill can say is put the parts in the truck with a note. I dont much care what I do its your truck and your money and as long as someone is paying Im happy.

theres much debate about what ford will and will not cover. I know they dont like seeing pyros in the pipe. so far they havent complained about exhaust mods. I just did one with 5" front to back and duel outlets. inspector asked me a few questions about pid data findings... I look at the guy and said hey dont know it had a P0603 came in on the hook with dead batteries and smiled. the inspector took 20 pics and a bunch of notes, ask me to stright edge the heads in front of him and had my ok to repair in 30 min of him leaving.

 

Cheezit:

If I recall, the way the Navistar / Ford thing broke up resulted in an agreement where there is a cap on Ford pushing warranty claims at Navistar.

So big bills can no longer be pushed back to the supplier --- and Ford is having to eat a lot of them --- especially with a Ford extended warranty involved.

I can understand (not that I approve) of what Ford is doing, trying to be real careful.

But in all fairness and honesty to Ford (and in their defense), they probably historically ate a lot of warranty claims from people who abused their trucks, ran tunes that way overstressed the components, and so on... and as long as they did not leave much of a trace, Ford / Navistar ate the bills.

That just can't continue.... that is why I strongly suspect that the new 6.7 is much more tightly locked down, and much more operating data is being captured and used to deny warranty claims.

All done quietly in background.. of course.

 

its not just a ford/navastar issue. Its an issue with numbers,claim dollars in parts and labor, repeat visits, etc.
for example you bring in a car for a squeek 3/3/10 and 1 month later for a water leak. ford sees that a recheck and it goes aginst a few catagories. its a bs system.
this is spred accross all car lines and borken up in to subsections. evey thing from focus to f550 is in there.

Ford has not only paid for damage caused by mods, but other techs inside and outside of the dealers. tons of misdiag and sadly a fair amount of the misdiag is there own doing. If you ever get a copy of the pc/ed look at how many pinpoint test say replace pcm. I replaced 2 of them sence 2003.
there is the whole oil cooler ordeal, we the techs told them they were wrong and they charged back 1000's of repairs for oil coolers only to come back later and claim them to the root cause.
the ect/eot split was at one time 25 degrees, now 15.
there have been revisions about cyclinder heads and now they say if they are cracked some cracks are normal. then they charge back the clain to the shops. would you want to eat $5000 woth of repairs. this is were a lot of issues lie.

 

Aye, Cheezit...

Ford don't seem to realize that sometimes the better techs out there know more than them...

They would have avoided a lot of pain retrofitting every 6.0 with the coolant filter... loss of face... but....

As for the FICM thingy.. could have put in much tighter monitoring of voltages / current to detect high current drain and damage...

As a electronics guy, I thought mounting the FICM box on the engine was a tad brain dead... exposing the electronics to too much heat, shake, etc. A engine compartment mount with some shielding and clean, cool air would have virtually eliminated the risk.


Basically, neither Ford nor Navistar knew enough about their products.

Looking how they did EGR cooling in the new 6.7, with the valve at the cool end...

I thought.. why not a cast iron cooler that is air cooled? That would have eliminated a very messy source of problems with the liquid cooling system.

Alternative would be to tap Exhaust gas from way back in pipe where it is much cooler... and use relatively inexpensive flex hose to pipe it to air intake and modulate it with a cheaper valve.


No wonder they got killed in misdiagnostics... with these design flaws.

 

Well,

I just got back from my near 200 mile round trip, and the blueish/greay smoke hasnt gone away.

I am with you Cheezit, I am thinking either a leaking injector at idle, or a leaking o-ring. I had my uncle follow me back to the dealer heres the shake down:

While driving there is no signs or smell of diesel smoke, pull up to a light and seh puffs some blueish/grey smoke. I pull away, it blows smoke for about 3-5 seconds, then clears up. He said the smoke smells like unburnt fuel, and looks like a 2 stroke outboard engine.

This truck had a Banks 6 gun on it when I bought it, the dealer sold it to me like that. I knew the PO and he never used it above level 3, so he said. I made sure I got it in writing that the warranty was still good, and that they would honor the ESP I bought.

I removed that six gun and PDA less than a week after I bought the trucck as per the techs recomendations. I guess I am paying for the PO mistakes now.

The truck hs no ill efects while running, fuel mileage is still good. The only thing left from the PO is the techni-cooler, and bigger elbow. I added a 4" turbo back exhaust with cat delete, and a CCV re-route kit from BD. I will be adding the coolant filter back in now that the EGR and oil coolers were replaced.

Ok heres the update, the truck went to the dealer last Saturday after the trip. They drove it, and drove it, and ran all kinds of tests to the injectors and EGR. They gave it the thumbs up so I went and picked it up, and picked up my boat this weekend.

When I first drove it the truck did the same thing, as the truck warmed it slowly went away, got to my destination and the smoke had totally stopped.

I think I am getting to the bottom of the smoke issues...heres my theroy:

When the EGR cooler went I foolishly kept driving it. It leaked to the point where I would see oily substance leak from the exhast clamps. I figure that the coolant/diesel condensation, mixed and settled in the exhaust and thats what casued the smoke. Today the smoke is all but gone, just a tiny bit while cold, but its more like condensation.

Next I will be getting the Dash Daq so I can keep an eye on those temps, and fuel pressure.
