Is this what you have seen from the SIDI V6 motor?
How does the carbon build up on the valve? Is it blown back out of the chamber as the inlet valve opens?
I wonder if a water injection system would help. It's a side effect I've seen turbo motors with water injection that they have clean combustion chambers when pulled down.
Carbon buildup is a problem on direct injection diesels more because of the EGR systems used which recirculate exhaust gasses into the intake for a 2nd burn. I pulled the whole setup off my land rover diesel when I did a VNT turbo conversion. It was really gunked up in there.
