I'm in the middle of rebuilding the top end on my '91 735 i and would like to know two things. Do you have to replace the cylinder head bolts ??? (I have seen conflicting info on this). Second, on torquing the head down. Do you first torque in two stages first with a torque wrench and then run the engine for 25 minutes and then torque with an angle of rotation guage while hot, warm or cold?
Any one with a Bentley Manual that can check this for me?
TIA
