My manual only has info on the torque sequence for installing the head, but no info on the actual torques or stages of torquing the head bolts.
My car is a 1981 528i. Any help would be appreciated. Thanks.
Head Torques
HEAD BOLT TORQUE SETTING 528i
My Haynes Manual says to torque the bolts in three seperate stages.
Stage#1 in lbs/ft; torque to 26 to 32.
Stage #2; torque to 49 to 52.
Stage #3; torque to 56 to 59.
The way I read it is to tighten each bolt in the sequence you're told as stage #1. Then start over going to stage #2, then stage #3.
When I put the head back on my '73 2002, I picked the # in between & stuck with that theme. Don't forget the Sam Adams sequence!
I hope this helps. I've had so much help from these good people. I'm glad to contribute. Enjoy,,,,GripGreg
