Valve Appearance - 496 BBC
While I had the intake off my 496, I noticed something odd. All of the valves look gummed up with blackish brown goop; something is not right....I think. At first I thought that maybe some oil that hadn't drained out had worked its way past the intake gaskets when I had the engine upside down to replace the oil pan gasket. But this stuff is sticky and doesn't wipe off easily. All 8 intake runners at the valves look like this. See attached pic; is this normal or are my valves gummed up already for some reason? Less than 1000 miles on her. Thanks for any replies.
