The solution to this is to take the intake off and blast the back of the intake valve with crushed walnut shells or similar media. This was developed in the early 80's by mercedes to fix this very problems on their turbo-diesels. VW, Audi, BMW, all have the same issue and need this service at 80-100k miles depending on the driving. Dealer approved procedure for them

this guy is a great mechanic,i don't know if he still works in a ford shop or not but either way he knows his business,his vids have helped me a lot.

I think the CATCH CAN is the best thing you could do for early eco-boost engines. The newer style engines have the dual injection systems. One injector sprays gas right in the cylinder and the other injector sprays the back of the intake valve and keeps it clean.

I said from the outset that the Turbos on the F150s are not worth the added complications they bring.

Why has it become common practice for manufacturers to push a product to consumers and basically let them (the consumer) test it? This is BS and the reason I dont buy stuff that just came out. I dont make a purchase until it has been on the market for a while and issues are found and corrected. Its total crap, and nobody (group or agency) will do anything about it. Every manufacturer is doing it too, its not a ford vs gm vs dodge/ram/fiat, its consumer vs corporation.

Toyota solved the direct injection by adding Bi injectors to each cylinder. There is a direct injection injector and an above valve injector. This allows the fuel to clean the injectors at 3/4 to WOT throttle.  I think Nissan does this to.

Since you can't change the injection system back to indirect so that the fuel can go back to acting as a solvent for washing off the intake valves, here's the simplest permanent solution... Need to install EGR and PCV deletes for all Ecobusts. It's also important to run a high quality 91 or higher octane fuel, without ethanol.

Would be interesting to see the BTU output of an induction cleaner vs the fuel you'd normally run anyway. Turbos deal with WAY more heat at 5000rpm than it would probably ever see with an induction cleaner. Towing a boat up a hill should get that turbo nice and toasty too. So the turbo would have to get extremely hot to cause any seal damage. The logic seems somewhat flawed to me.

The carbon build up is still very common on turbocharged petrol BMW's

You may b interested: purchased new 2004, Supercrew, F-150 Lariat, 5.4, in 2004…. The only problem I’ve had so far is Dealer Improves…. so I determined that this vehicle will last a lifetime if: use high quality oil, monitor mis-fires, then chk. Coils, injectors & keep clean Air filter.. all is good; however I do have Trany fluid changed every 50K and have an additive added to keep seals tight. I do get: 21-26 mpg on byway., 18-19 mpg in town. I pull apps. Weight of 2,500# frequently…. Also, I do add Seafoam every other month to fuel, does keep the carbon in chk…. I love this F-150…. No cam phaser problems yet..
