Hi Guys

I am a noob with with direct injection engine.

I read that these direct injection engine can build up carbon at the intake manifold since no fuel is sprayed at the valves.

Any tips to prevent or slow down these build up. Some people suggest Oil Catch Can.

My car is a basic 2L N43 engine so not even turbo charged. I was quiet lucky the last owner had the engine replaced under warranty only 15k miles ago. Saw the invoice was £7k.. OUCH.
Would like to keep the engine sweet and trouble free as possible.

I do about 8k miles per year and 95% is local traffic driving.

Do i need to worry about carbon build up and anything to slowdown this process guys
