So I was wondering... Was it assembly lube that charred and stuck to the face of that rotor, was it an oil injection problem? It is also possible that this rotor face had a stuck side seal (it did not come up when pressed down).
I did not polish the rotors on the engine I have in the car now. Maybe I will look at them after 13,000 miles.
ReTed, You are completely right about the factory coating. I found that the 9.4:1 rotors that I put in the engine the second time were coated. The only place that carbon had stuck to them was in the combustion chamber 'bathtub' and where the coolant that was regularly floating around in the engine (bad coolant seals) had caused the surface to rust. I have had two other NA engines apart and many turbo engines and have never seen that coating until this time (although I may not have been expressly looking for it).
