Message	The color is ash deposits from burning oil, not a lean condition. The burnt oil deposits take up space in the cyl and can cause the compression to be slightly higher as appears to be the case in your engine. Either a oil ring is not sealing, or a valve guide is leaking. More than likely is a oil ring and could still end up sealing. I would recommend finishing the break in and see if it clears up.
