white smoke need help

[sanbar21jb]

ok guys here you go, its an 07, with a tuner, 4" turbo back, afe direct fit filter, the truck ran great up till today now i got white smoke, it first started when i would back off the throttle and now it is progressively getting worse i drove it strait home and poped the hood, i heard a hissing noise comming from the passenger side of the truck back by the fire wall, it does countinue to smoke while at idle, but when driving there is none. till i got home i could tell at a low rpm there was a slight miss or bucking but when the rpms got up it was fine. i did put 2 new batteries in it today

thanks for all the help any questions u have to help me diagnose my problem just ask

It sounds like an egr cooler bad

i do not smell a sweet smell but i can feel moisture when i put my hand at the tail pipe

look for coolant loss (not a leak - rather being run out through the exhaust) and then park the truck nose down overnight. Pull the EGR valve and observe for moisture. Sounds like a blown EGR cooler, but this will tell you for sure.

Mine is at the dealership right now getting a new egr cooler in it right now. Didn't blow white smoke. The only way it lost coolant was puking through the degass bottle. Some times the only real way to tell is pull the egr cooler out and pressure check it or submerge it under water. Ford can tell if the egr cooler is bad by putting it on the computer but they still pressure check it and stuff when they pull it out to make sure.
