I 100% agree direct injection alone is no good, that's why I like what Toyota did and implemented both, the ability to achieve the high efficiency of direct injection while still achieving the cleaning benefits of port injection.
Catch cans can be harmful in cold weather as the fluid freezes in the can causing the crankcase not to vent and blowing up the engine. There is a good reason the manufacture does not install these at the factory. A VW dealership mechanic told me this is not a problem in Germany because the fuel is so much better there.

Walnut blasting works great

Forgot to mention the massive amounts of oil consumption
Have been cleaning with steam/vapor while running the engine, it works but starts building up again fast
Intake walnut blast, look it up. Helps a lot with cleaning carbon out those ports

How about we stop pumping exhaust back into the intake?
They do intake cleans with an intake fogging system while it’s running.
