I was told that it is the additives from the oil and not to worry about it. The crud in the photos above came from Brad Penn oil and was not soluble with mineral spirits. The mineral spirits just moved it around but the pan cleaned easily.
The only thing in my engine that is black is the spacers between the T&D rockers and they looked perfect when inspected. Also the engine was clean and everything looked great. It's ran great all summer, I did change to Driven oil.
If this is true, that's bad. If the additive package is falling out of the base stock it's useless.
I've seen things like this before. Using a real synthetic with alcohol will do the same thing. When you drain the oil the alcohol has separated out part of the VI improvers. The oil pressure is no longer stable, and you start getting blued adjusters and other things.
I'm not sure what part of the additive package that black residue is, but that would be very disconcerting to me.
