Message On cylinder 6 there is a 10% loss, I cannot hear anything coming out of the valves only the crankcase. Mind you I have the oil pan off, not sure if this skews any readings?

The valve seats seem to be all gummy looking, not a shiny patch where the valves have been contacting the seat. Lots of carbon too, wonder what is causing this. I'm using what is supposed to be a top-tier gasoline (Chevron with Techron 94 octane).
