Just typed a big post and lost it
Lost my post.
Still the best place to go for info on our trucks.
The truck; 2006 F350 CC 6.0L, auto, Edge tuner, cat gone, see through muffler, EGR blocked off, CCV reroute to road dump,K&N filter, Garrett Power Max Performance Turbo (GT3788VA), Stage 1, from KT Performance
installed just before leaving home.
The problem; after setting for a month I took the truck out for a driver while I worked on the Jetta, after several hundred miles of use I now get a white smoke at idle. Coming into the park at idle all is well until I hit the first spped bump then it goes to smoking, can do a light rev to 1200 and it quits, until I get to my space and it starts again. Can smell any sweet smell or acid smell and no burning eyes, can't define any particular fuel or coolent smells at all. No loss of coolent in over a year, no excessive coolent pressure, no loss or gain in the oil level, no excessive road draft fumes. Pulled the egr valve and it is dry, no coolent or oil, and has just a light dusting of dry soot. Manifold below the egr os the same. Pulled the innercooler to engine tube (the top one) and it is dry as a bone, did a FICM test and it is 49.8 volts. Set up the edge to read ECT-EOT and after a warm up run had 188 water and 200 oil for a five mile slight uphill pull, then a 186 water and 201 oil for anothe five miles on the same uphill pull. When driving slower (15mph) the water goes to 186 and the oil goes to 194, then idle into the park and it hits the first bump and goes to smoking, light rev and its gone, then it sometimes smokes when I get to my site and sometimes not.
What is my next step????
Thanks for any help offered.
Did I stump the experts?
Should also correct the post by saying that I cannot determine from the smell of the smoke any hint of coolent or fuel. Smoke is white with a very slight hint of blue, like oil smoke.
Talking to KT Performance
now to see if they have an answer or solution to my problem.
I've got a similar issue, except no bump needed. AE tests show no issues. I've had a high amount of smoke at first start with a blue component. No visible issues with the EGR passages. Pulled the turbo and no issues with the oil seal. Put on my spare new turbo and no change. Talked to the truck assistant service manager who I've known for years and he said change out the EGR valve even though it tests and looks good.
That took care of the large amount of smoke/vapor at initial start. But now I still have residual light blue smoke, some when driving but occasionally a slight to far amount of it at stops until the motor is up to 190.
When I try to read the first page of this thread I get a weird message on the screen then it kicks me out of the TDG site, this only happens on the first page of this thread, no other threads, so I can't read anything to answer anything.
To Largecar...maybe start a new thread about your trucks symptoms, then I can read it.
Is anybody else is experiencing this in this thread?
And that is why I am doing this copy paste stuff because I am a old fart that does not know how to do it a better way.
No problem viewing for me. But it's an old 2013 thread with Largecar adding to the thread at message #8.
sent me this email:
"Did you check for leaks with the intercooler and up-pipes? That is a common failure for loss of boost pressure."
I checked the exhaust side and found only one little soot trail at the clamp into the turbo, not enough to be of concern, no smell in cab. No leaks on the pressure side, checked all the hoses and pipes, inner cooler held 10 psi for over an hour ( I made two aluminum plugs one with a metal valve stem to put air in) and checked from turbo out to engine in. Just got back from my buddy at the Ford garage and he discovered that the turbo is slow to build pressure, said maybe the stator ring (I think that is what he called it) was binding or not smooth. He also said the smoke smelled to him like oil smoke and it had a slight blue tint to it. He also discovered the smoke came on quicker when idled in gear over idling in neutral or park. He said that the slight amount of pressure against the engine is what the difference would be. The truck has had the CCV vented to a road draft tube since almost new, so the hose into the manifold is dry, no oil residue. So we think the only place it is coming from is the turbo shaft seals. My question is would the seals work better with the turbo making pressure and not as well when it is in a not pressure state? I don't know so I will leave that up to the experts.
You might remember me as I sent a couple of emails to you just after I installed this turbo with complaints of low boost when towing my fifth wheel. I kind of got used to the way it functioned and quit worrying about it, but now it is a whole different set of circumstances. We pulled the fifth wheel out to Arizona and put the truck under a cover, only using if about once a month just to keep fluids circulated. It was this months run that the problems started. We will be going back to Oklahoma some time toward the end of April and don't want to worry about being broken down somewhere.
Let me know what your thoughts are.
That should bring us all up to date, thanks for the patience.
