You wont quit will you.....all catchcans are not the same, and no catch can causes fuel dilution...it is impossible, RX or other.
I think his pictures show pretty much "real world" and the fact that this is what we do....build and rebuild engines, and every picture except yours shows the gunk build-up.
The gunk buiuldup is caused by the oil ingestion.....trap the oil before it is ingested and you have no buildup plain and simple.
And it has been pointed out over and over again "NO FUEL TOUCHES the intake side of the valves where the gunk deposits form.....so it does not matter what fuel is used on DI motors. The fuel is introduced directly into the combustion chamber on the only in the combustion chamber for a milisecond. For a top tier fuel, or fuel additive to have any effect on keep valves clean it has to be a port injected or carburated engine where the aitr/fuel mixture passes the intake side of the valves allowing it to contack the sureface where the deposits form.
