Answer 4

70-75 ft lbs. be sure you go in the right order. and torque them in steps. First torque them in order to 25 ft lbs, then start over and torque them to 50 ft lbs, then start over again and finish them off to 70-75 ft lbs. Be sure to coat the threads in engine oil before you screw the bolts in too. The will not torque right if the threads are dry.
