    One or two might be in the doc, but it is always good to check the online TIS for the full instructions which mention special procedures.

    Anything with a rubber bushing, a metal sleeve and a bolt going through it needs to be torqued at ride height.

I remember bimmerfan08 broke one of the M5 bolts trying to torque it to an approx. value. After cross-referencing the two bolts, I saw that these bolts are also used on the E36 and other E46 models.

        According to the TIS for the E36 and E46, the M5x16 (number 6, pn 07129903041) is 5NM and the M6x16 (number 11, pn 07119904524) is 10NM.

        S54 oil pump is on page 49.

        The TIS seems to also state to wash and oil the replacement M10 rod bolts before installing.



        Thank you for this. I was also a victim of busting one of the M5x16 bolts torquing it to 10nm. FCP actually recommends this in their video which is what I went with since I couldn't find a spec. Had to get it extracted, super fun.

          The torque spec for the transmission is questionable: It said M12 for the bolts holding the gear box to bell housing with the spec 76Nm or 56 ftlbs. This torque seems too high and can damage the bell housing. Where did this information come from?
