pukes white smoke

[z71remi]

08 F-250 with 15k miles on it. No mods just stock. Motorcraft Cetane (4oz) every tank.

I pulled out on the highway after fueling up and stepped on the gas to get up to speed quickly(New gas station). It died and blew white smoke every where only for a few seconds. Started to pull to the shoulder and then it kicked into gear and hauled a**. I noticed I was getting 2 more mpg's for like 50 miles afterwards. After 50 miles it went back to getting the regular mpgs. Never acted up again for a while.

Last week I drove the truck for the first time in a month and everytime I stepped on it there was white smoke. The engine was well warmed up before I stepped on it. I do not constantly step on it, only when I need to.

I have checked the fuel water separator and very clean fuel. Got my oil changed and even technician said my fuel was as clean as it gets.

I plan on putting mods on it when I reach 20k miles. However, I dont want to put mods on it if there is a problem with the truck. Other than that the truck act excellent and is fine. Just worried about the white smoke and dying for a few seconds.

Anybody ever experience this. Insight would be appreciated. Thanks ahead of time.

well i have straight pipes and mods and when i run it stock witht eh straight pipes its puffs white smoke in regen maybeee ur dpf is cracked and screwed up? idk lol

Was it in regen? Had it been raining or high humidity? Cracked DPF, Intercooler TSB, or EGR problem, come to mind, but need more info. With 15K on it and no mods, I'd go to the dealer and have them check it out.

with only 15k on the truck and no mods, just go to the dealership. You are well within the warranty

After I wrote this thread I read something about changing the air cooler assembly. It mentioned about this happening when driving at a constant speed and in moist conditions. Well the first time it happened it was driving on the highway for about 2 hours then stopped to get gas for about 20 min. Then got on the throttle to get on the highway and poof! The second time was sitting in a parking garage for about 7 weeks and not started. There was moist days in those 7 week so dont know if that had anything to do with it. It was talked about driving in rain but now sitting in wet conditions (truck was covered).

I am not worried about the warranty but dont know what they can do if they dont see the problem because it doesnt happen often. I will take it in and see what they will do. The info I have on it is TSB 08-21-1

Thanks for the help gentlemen.

My 09 does this almost every day. I travel down I-10 from Beaumont to Baytown. I get off on 99 (Grand Parkway) and there is one stop sign I roll. I get into the throttle and POOF, it falls on its face and blows out a cloud of white smoke. I always thought it was just collection from the DPF. I need to check if it was built before 10/1/08.

Driving in the rain or high humidity is the cause of the accumulation, but the white smoke and reduced power can happen anytime after that moisture builds up, depending on the situation. I had it happen the day after driving in the rain. Thinking back... it was 20min of highway then pulled off into the driveway. No real acceleration to kick the water up. The next day, it was sunny and nice. The water was still sitting in the intercooler though. Went to pull back out on the highway and poof. 35mph, no accel, fogged the road.

One dealer wanted the truck for a week, to wait for rain.... another thought that was ridiculous and just did the TSB with no problem. Pay attention to your boost levels now though. I'm wondering if after you get the TSB done, you notice lower boost at a given load. Mine runs a few pounds less than it had previously with the old one.

Can you check for a part number on the side of your intercoooler? It should be on the passenger side, a white sticker. Thanks!

Does your sticker have 3 part numbers?

It's the number with "CAC:" before it, if so.


My old one was: 7C34-6K775-CG
