heres the story...my boyz are starting my build up on my jdm h22a for me while i get through with summer school finals..well they tore apart the block and noticed the main bearings were different colors...we usually work with b series motors so heres the question...is that normal on a jdm h22? or has the bearings on this motor been replaced before...the motor prob has about 30k miles on it...so it seems kinda odd if the bearings have been replaced before.

 

b-series motors are the same way.

 

Yes its factory, it done on b-series sometimes but its more common on preludes. Get a prelude manual and it will tell you whats up.
