Hey, Bruce! Good to hear from you.

Saw the comments on the rope trick. Keep in mind that the torque in the crank results from combustion pressure on the piston. Does the crank bolt require as much torque as is produced at full throttle? Probably not... (And don't be fooled by the notion that the torque results from four cylinders -- only one fires at a time.)

So, if less torque is required to loosen-tighten the bolt, then performing the the rope trick imposes less pressure on the pistons, rods, and bearing surfaces than occurs at full throttle.

Just my nickel's worth...
