What is a lifter for Camaro?

A lifter in a Camaro is a component of the engine's valvetrain. It helps open the valves to let air and fuel into the cylinders, and exhaust fumes out of them. Lifters are usually cylindrical-shaped and made of metal. They fit inside the engine block and push on the valves to open them. The lifters are actuated by the camshaft, which rotates and forces the lifters up and down. The lifters also contain a small amount of oil to help reduce friction between the lifter and the camshaft.
