I tend to call it the TVIS effect..... While the TVIS butterflies likely have some effect, I believe it also has to do with the offset injector port............




Note valves 1, 4, 5, and 8 are more heavily coated in carbon, they are NOT sprayed nearly as the other valves by the injector placement.

It is similar effect that direct injected engines suffer - large build up of carbon.



Port work begins.... 1 and 2/3 down........





more to come........
