Couple important notes on this setup:
- Direct injection can, over time, suffer from carbon buildup due to the absence of cleaning agents on the exhaust side of the intake valve. You'll notice the injector spays fuel on one side of the intake valves only; so traditional fuel cleaners do little to remedy this issue. Modern DI motors have changed their configuration to minimize this issue. But it may still be a problem on high mileage motors. Use good quality oil (for blowby) and fuel high in detergent.
- Turbo motors benefit greatly from PCV catch cans. In short, blowby from the PCV system sends oil mist and gasoline fumes through the intake manifold, which accelerates buildup on the intake valves. A catch can collects this blowby to help limit buildup on the intake valves, 02 sensors, and cats.
