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 the bolts are removed and reused, it may cause the bolts to break or fail to maintain clamping force.
