:) Hi, you don't know how many engines I have worked on????? My first overhaul was on a Ford V-8 Flathead. I was a mechanic in the Army. Then I was a new car dealer mechanic since 1968. I have touched a few engines in my time. In the late sixties and early seventies, Big V-8's had huge carbon problems. Retired from a Ford dealer in 2008.
What's your experience?
How many were DI gas motors?
Top tier gas is formulated to help clean the intake side of a motor. Injector and intake valve cleaners same thing. Doesn't prevent, but limits build up.
Impossible to do with the standard DI motor as the fuel and cleaner never touches the intake side.
Now introduce an EGR port like on Ecoboost. More junk and crud to build up on in the intake and back side of the intake valves.
Just like in the old days, go out and run them hard to "blow out" the carbon helps. Yet the build up is more because there is no fuel washing over them to help clean.
Carbon build up on the intake valves building up tonthe point of not sealing causing loss of power etc...
:) Hi, "How many were DI gas engines?" (motors are electric) NONE.
We are still talking about carbon on the valves. Old history.
