Carmel Cylinder Bores

[infinity5]

If there were carmel color streaks up and down the cylinder bores of an engine, what would you say?

Oil deposits. Got a pic?

varly normal depending on how much is there, it's usually due the bores being slightly out of round from the stress of the head bolts. that's why some people use a torque plate when honing the bores to simulate this stress and get a better finish, it doesn't mean your motor is bad
