So in December i took my 2009 F-250 to the dealership due to an oil leak. The stated that the front cover gasket was bad and needed to be replaced. So a few hundred dollars and three days later i get my truck back. So then another week goes buy and i'm at my hunting lease. Out of no where while i go to take off, a large billow of white smoke comes from the tail pipe and i have complete loss of power. I immediately look at my boost gauge and have zero boost. And before i can even stop the smoke stops and the power comes back. So i didnt think to much at first and it drove fine for several weeks. Fast forward to the end of January. I go to take off and again no power at all and a huge billow of white smoke comes out. Completely covers the street and you cant see through it. So a second time i take it to the dealership. They tell me after two days that the turbos are completely destroyed and the smoke it from the oilers in the turbos. So another few hundred dollars later and 8 days i get my truck back.

Then today im driving my dog to the vet and the exact same thing happened but this time not only was there a loss in power but the truck seemed to sputter. Every other time engine runs fine. No banging knocking or anything else. Just acts like theres no boost.

Any ideas guys????

 

Stop changing parts. It only confuses things. Cause and effect. You change something and it causes something to happen. The more parts you change the more uncertain you become on what is causing problems.

You had an oil leak from the front cover (not uncommon) and a tech changed the front cover gasket. No idea if they also changed the front seal but never mind. So the tech touched ....

- Front cover
- oil pump
- Radiator and radiator hoses
- CAC and CAC boots
- Vertical EGR cooler

And you now are blowing white smoke from exhaust at times. Sometimes its accompanied by loss of power. They tossed a new compound turbo on your truck along the way, which did not fix the white smoke problem but didn't cause any other problems. Right? Also the oil leak is fixed. Right? No trouble codes. Right? Stock truck right? No changes in fluid levels (oil, coolant) right???

So, go back to what the tech messed with when they fixed the oil leak. Which of the items could cause white smoke? I think white smoke is either fuel or coolant. So, based on what was touched to fix the oil leak I'd:

- look for a coolant leak in an EGR cooler
- I'd drop the lower CAC boot and look for moisture condensation
- I'd inspect the EBP sensor (fueling) just for giggles
- I'd probably think about the EGR valve sticking
- I would closely monitor oil and coolant levels for any changes

So, there are some things you can look at. Kinda wonder if your dealer hasn't already done these things. But all of them are things you can do in your driveway as you figure out what is wrong with the truck. Best of luck. -FB

 

I agree with the above. Make sure you get a solid diagnosis before changing anything.

What were the weather conditions and were your trying to accelerate hard? Sounds like it could be condensation in the CAC.
