NOTE:
Torque-to-yield cylinder head, connecting rod cap and crankshaft main bearing cap bolts must be replaced once removed because the bolts are designed to be permanently elongated beyond the state of elasticity when torqued. If removed bolts are reused, the bolts may break or fail to maintain clamping force.
