White Smoke NOT FROM Exhaust

[eneranch]

During REGEN I've been experiencing a lot of white smoke coming from underneath the front of the truck, not from the exhaust, when I come to a stop. It smells like a dirty BBQ smoke very strong, it will come through the vents and fill the cab. It seems to be coming from underneath the right side front passenger door area.

Has anyone seen this ??

hows your coolant level? is anything loose and maybe touching the exhaust? during regen, the exhaust temps go WAY up so maybe something is touching it and only burns when regen occurs.

I was finally able to get underneath the truck without having to take it out of drive (that sometime stops the REGEN) and take a look.

Seems there is an oil leak somewhere above the exhaust, and the only time it smokes is during REGEN; next time in the shop I'll have them fix the leak.

glad you figured out what was happening

Mine is doing the exact same thing. The smell is awful but I don't seem to have any leaks anywhere. Where does it appear to be leaking from on yours.

I didn't know somebody already started a post on this. I just started a post on my truck cause its doing the same thing. I don't know what it is but I'm glad I'm not the only one thats having this problem. I wish Ford would come up with a solution, cause like you guys said, the smell is awful.

My truck took a dump last Thursday; had it loaded onto a flat bed & taken into Ford.

Got a call on Friday with the news:

The EGR Cooling System had failed and was allowing Coolant into the Engine Oil or Engine Oil into the Coolant; in turn damaging the Oil Cooler & possibly the Intake Manifold. Evidently the fix will take at least 13 Hours of shop time.The white smoke I was seeing was caused by Oil-Tainted-Coolant leaking from somewhere in the EGR System and falling onto the Exhaust System; during REGEN the extreme temperatures would cause this fluid to produce white smoke.

I just got off the phone with Ford for a 2nd Update : The whole Intake Manifold & connecting gear had to be removed and thoroughly cleaned to be sure all of the burned-waste oil/coolant was gone & during the Tear-Down process the Technician noticed large amounts of Soot forming on the outside & inside of the Tubing connecting the Inter-cooler to the Turbos - evidently to fix this problem one has to drop-the-tranny to access the system.

Soooo - I am told the truck should be ready sometime Tomorrow; that's assuming they can find & fix the Intermittent Cruise Control Problem I've been experiencing for the last year.

If anyone else is experiencing White Smoke coming from under the Firewall Area and filling the Cab - take it to Ford; they have seen this before.

well in that case, ford told you backwards. the oil cooler took out the egr cooler. The oil cooler becomes restriced, causing the egr cooler to fail because the coolant flow goes from the oil cooler to the egr cooler next. usually when that happens, there will be white residue around the degas bottle cap and you can usually hear a low howl on deceleration which is pressurized cooling system gas escaping from under the degas bottle cap. wish I couldve told you sooner. glad you got it fixed tho

if the egr cooler blows coolant gets hot and will take out the oil cooler.i have replaced many egr coolers and had no oil cooler problems.it doesnt matter what is before what it all still runs through the same system

also i have noticed when oil cooler goes out the front cover is cavitatied. the cooler gets clogged and blows due to metal from the front cover.either the cover is also bad now or it has been recently replaced.
