BMW cylinder torque setting all models
According to my service manual as follows.
Cyl head to engine block (torx e12 M10 bolts)
Stage 1 30nm (22 ft – lb)
Stage 2 + 90 degrees
Stage 3 + 90 degrees
Cyl head to lower timing chain cover 10nm (89in – lb)
The tightening sequence is from inside to outside crossover as normal. Loosening sequence is from outside to inside crossover. Remember to set torque wrench at low setting and work gradually up through the whole sequence until you get the desired torque.
