Interesting video. But I wonder what this guy’s background is. Clearly he’s a paid PR guy for Ford.
I have a problem with his statement that it isn’t a direct injection issue and his statements that all engines whether DI or port injected will have the same carbon buildup. He then talks about all the things that Ford is doing for the future to deal with the carbon buildup problems with direct injection. These are contradictory. He can’t have it both ways.
The guy has a decent act. But I’m having difficulty believing him. And he’s clearly a paid Ford salesman.
I myself considered the “bearing wash” possibility, albeit with the caveat that the bearings should be sealed against any such penetration. And turbos can be made to glow. They spin in excess of 200,000 rpm and are heated by the exhaust gasses, which when the engine is revving can get extremely hot. The video shows no evidence that it’s being caused by the induction cleaning process in any way.
I accept that turbos might be damaged by induction cleaning. But I cannot give credence to this video. Sorry.
