Review on Dorman 74114 Camshaft Bolt by Jason Wilson

These bolts are yield point bolts that must be replaced with new ones every time you remove a camshaft secured with this type of bolt, such as GM in various vehicles. When tightened to factory specifications, they will stretch to the point where they can no longer be used. These Dorman bolts are well made, readily available and cheaper than buying OEM bolts from a dealer. They are sold in packs of two screws - both are required. Don't risk engine repairs. Buy a bag and put it in the glove compartment; If your Ecotec engine fails after a few years of service, you'll be glad you have it.
