Abstract
Methods and systems are provided for a valve spring retainer of a valvetrain assembly. In one example, valve spring retainer may be at least partially hollowed and include inner cavities forming channels within a material of the valve spring retainer. Air inside the inner cavities may be fluidly coupled to air surrounding the valve spring retainer through channels. A mass of the valve spring retainer may be decreased and a cost and speed of fabrication of the valve spring retainer may be reduced by additive manufacturing.
