Hi all,
I'm about to reinstall my head and I'm seeing conflicting answers on what head bolt torque should be for the 14 M10 torx head bolts.
BMW's torque manual (http://www.e38.org/bmw_torq.pdf) says it should be 30nm, then 90deg + 90deg with no settling time and no warm running time
E30 zone (https://www.e30zone.net/e30wiki/inde...orque_Settings) says 30nm, wait 15mins & tighten additional 90deg then another 90deg with engine at normal working temperature
Anyone know which is right? Is it mandatory that I do the second 90degrees with the engine warmed up, or should I follow BMW's directions?
Thanks,
Mike
