Re: Rod bearing crush too much?

does the steel backside of the bearing have some type of flash coating rust preventative measure applied, or is it bare metal?

a lot of times they are processed with something or other.

who is the bearing manufacturer?

chances of the intake guides being even remotely worn are slim to none.
