Some thing just isn't setting well with me about this video. I mean its sound like these EB engines are doomed. How could ford design a engine, that remedy to fix is to replace the head. No method or procedure for decarbonizing, Really! Any how there is some relevant info here, yes spraying foreign material in to turbine at speed will damage turbo. But I don't see how doing regular maintenance with product BG service doing any harm. For one turbo's are not at speed when performed and two as I said regular maintenance so the means you already don't have any large build up of carbon. So no risk of a big chunk of carbon flying into turbo. Now if you have a engine that is totally carbon'd up other method would have to be employ'd, such I have seen companies media blast cylinder head right on car with intake manifold removed with walnut shells. Now with the F150's sounds like they have a complete different set of issues, with moisture or other debris that manifests its self in the intake tract that is damaging engine and turbo's. I wouldn't put to much into this video, just my 2cents.
