Use good fuels and fuel system cleaners maybe once an month to every few months.

This won't stop the problem, but it will help minimize it.

I know there's lots of people on some of these threads saying this won't make a difference, but that just shows their knowledge of engines. Even though fuel is not squirted directly onto the valves. A certain amount of exhaust gas and injected fresh gasses do go in and out of the intake manifold. This is known as scavenging in an engine. This and oil from the crank case that are put into the intake for emissions purposes are what the buildup is from. And this is why oil catch cans were invented.

There are other ways to bypass this oil getting into the intake, but they are a lot more on the illegal side of things. And lets not forget, some oil does bypass the turbos, so it is unavoidable to a certain extent.
