Marvin torques main caps in third values. Accepting torque value is 60-70 ft-lb, which means he torques these bolts to 23 ft-lb, then 46 ft-lb, then a full 70 ft-lb. With each torque, he checks the crankshaft for freedom of rotation. You should be able to turn the crank with your fingertips or the weight of a breaker bar. Threads should always be lubricated and free of damage for accurate torque readings.
