White Smoke

[FLS351]

I have had my truck for maybe a month now and this is the 4th time this has happened. The truck idles up to around 1100 RPM like it is going into Regen, but it stays there until I shut the motor down, because the idle never drops (8-10 minutes). During this high RPM idle, white smoke starts to blow up from underneath the front 2 doors of the truck and from the engine compartment. If I dont close the A/C recirculation button, the cab fills with white smoke. This smoke is not coming from the exhaust tip. After the first time, I took it to Ford and they reflashed the computer. It did the same thing and I took it back. They kept it for days and drove it with a laptop hooked up to it and said everything was perfect (which I dont doubt at the time). This is an intermittent problem. I am taking it back to Ford this week again. Does anyone have any idea as to what this might be? I assume it's something with the Regen process, but obviously something is malfunctioning. Thanks in advance for any input!

one thing to know , is if you do not let it finish doing an regen then its gonna continue to try to do one , if it continues to build up it will smoke pretty bad ,as far as smoke from under cab , you may want to tell them you think you have an exhaust leak, i havent seen it much yet , but there is a bulletin about the clamp on the turbo and gasket replacement for something similiar to what you are talking about,

Ok, we'll see what the come up with. Also, when it is going through this high idle and I shut the engine off, I hear the womp womp womp noise others are describing. I only hear that noise while I am smoking and shutting the engine off and no other time, so I don't think its the fan.

thats noise is probably coming from the turbo

sounds like a exuast leak right after the turbo
