according to the prescribed pattern  and then a second  tightening by 
another 90 degrees in the prescribed  pattern.>>


BMW issued a bulletin about nine years ago revising  the method to 180:. I 
have found that to "feel" much more consistent.

I  guess the real proof is that I have never had to replace a head gasket for 
any  of my customers who had leaks. I just give a normal retorque and they 
are good  to go. The leakage stops.
