A rocker arm for an internal combustion engine is provided with a hydraulic lash adjuster located therein. The rocker arm comprises two portions rotatably mounted relative to each other with the hydraulic lash adjuster located therebetween. The hydraulic lash adjuster compensates for any slack in the valve train and rotates with the rocker arm about the rocker arm's axis of rotation rather than move linearly along the pushrod axis as in prior art systems. As a result, hydraulic lash adjuster wear, valve spring force, engine friction, and fuel consumption may be reduced while not decreasing the valve train toss speed.
