im about to take on the challenge of rebuilding my motor, with the "basic engine rebuild kit" from AMS ... im not a noob to engine assembly but just a noob to 4g63 engine assembly... doin some research on this hole thing a found something sayin that the engine bearings are color coordinated. but there was nothing clear on what this ment.. and if the kit comes with new bearings must i mic the old one as i take them out and match them to the new ones the best i can???or can i just drop in the new bearings "plasti-gauge" check them???by the way no crank damage, this is just a preventative build
