F650 Head Gasket replacement problem
Greetings BMW tech gurus ...
I need some advice. I just finished putting the engine back together on my wife's 2000 F650ST after a nasty overheating experience. Long story. I had both the head and the mating cylinder faces re-machined. Head vacuum tested. New head gasket. Meticulously reassembled. Adhered carefully to torqueing procedure, yada yada ... She started up on the first kick, ran beautifully for several minutes and then slowly started blowing steam. I'm obviously getting coolant into the cylinder. Clymer recommends loosening and re-torque of all the external head bolts in this situation but I'd appreciate any additional perspective on this. Can I "over-torque" the 4 primary head bolts? Thanks in advance.
