Re: 1988 Olds ninety-eight issues
torque to yield bolts usually aren't torqued to a set torque number, you tighten them to a low torque number then turn them like a 1/4 turn then another 1/4 turn or amount the book calls for. when you do that the bolts stretch some and the elasticity of the bolts keeps the head on tight. when you remove them they may not shrink back to original length so if you reuse them they can snap or not have the elasticity they had when new so they want you to replace them
