    m42 main bearings

    Im trying to decifer what main's I have in the block right now... RealOEM shows a similar number to what I have on the back of my bearing, but its different anyone know?



    I think Ive mixed them up, but the bottom or top was like this



    1717 523 8522

    524 / 525 other side 07/90 <--assuming thats just a prod. date?





    the other half...



    1705 275 7391

    276 / 277 other side 04-89 <--same deal prod. date?





    Anyone have a wealth of BMW engine knowledge??
