You mention 'second round of torqueing' - AFAIK this model does not require such a process - the book says tighten gradually in sequence with a finish torque of 65-70lb/ft on bolts 1-10, and 40-45 on bolts 11-14 (AKM3621) - on these last 4 you might go with the 25lb/ft given above. If you have tried to do a tightening involving a torque and then some angle tightening that might explain the breakage. Elsewhere Ron relates that LR now specify to lightly oil the bolt threads, rather than use a special sealer/lubricant. I once had to pull a RR head due to it swallowing a carb needle retaining screw, and a rear bolt snapped off flush with the block as I undid it - the stub unscrewed easily once there was no load on it.
So your saying I should tighten all the bolts to the 65-70 ft-lbs in one go but follow the sequence of the bolts tourqe process?
(I'm not exactly sure what angle tightening is could you please explain)
and with the oil on the threads...can this just be motor oil? Or will I need a specific type? Thankyou
