Avoid induction cleaning on ecoboost engines

I thought this may interest people on the list. Apparently ecoboost engines are getting a lot of carbon build up and people are doing something called induction cleaning (I've never heard of it) that involves spraying some cleaner in the induction. This causes extreme high temps in the turbine and kills the turbine:

the carbon build up is a warranty repair but turbine damage from induction cleaning might not be covered.

In the second video on that page the mechanic doing the video points the finger at the EGR valve feeding oil into one cylinder.

I'm assuming this doesn't apply to diesels. But since Ford was first out with these small turbos it may apply to the newer GM and Dodge light turbo engines.

  • This really isn't much different that the carbon issues on the newer diesels ('07.5+).

    Easy fix. Drive it like a truck every once in a while. Driver's who never get on it should probably consider downgrading to a less powerful motor.

    Even my V10 develops carbon problems after too much in town granny driving. 20 miles with the trailers gets it running like new again.
  • A few people and myself talked about intake valve carbon problems on this forum way back when the EB first came out.

    I believe I was called an alarmist by people that had a whole 20 thousand miles on their new trucks. :S

    BTW that tech must have a magical engine. Every time I add more of a hydrocarbon to any of my gasoline engines it runs cooler, not hotter. :h

    The problem with the EB is not carbon on the EGR valves, it's carbon on the intake valves. A much more serious and difficult problem to correct.
  • The problem seems to be linked to short trips that don't allow the engine to come up to operating temp.
  • A co-worker is on his second Ecoboost F150. Traded the first at a little over 100k miles. This one is nudging 40k. No problems so far. He uses his for a work route vehicle and a tow vehicle for his TT and dirt bike hauler. His is why I'm considering an Ecoboost powered F150 HD for our next 5th wheel hauler.

  • A few idea's..
    Would it be cheaper to do the forced induction cleaning and just replace the turbo's rather than go through all the expense and labor of replacing the heads? Which is more costly?

    Pull the turbos before induction cleaning. A lot of work but cheaper than the alternative.

    Or, Ford needs to come up with a program that opens the wastegates during induction cleaning so the turbo's aren't forced to work so hard. The program could alter timing and injection events to help keep temps under control.
  • It is good to know that the repair is covered. I would tend to guess that anyone spraying in something that is flammable would not be covered when it blows up!

    Have fun camping!

  • Thanks for the post. I just bought a 2014 ecoboost. Not sure if mine'll carbon up, :) :) :) but good info
