Abstract
Methods and systems are provided for oil flow for hydraulic lash adjusters of a vehicle engine. In one example, an engine cylinder bank includes a plurality of deactivatable hydraulic lash adjusters and a plurality of non-deactivatable hydraulic lash adjusters. A first linear oil supply passage and a second linear oil supply passage are formed within the cylinder bank and extend linearly through the cylinder bank without bends or curvature to the deactivatable and non-deactivatable hydraulic lash adjusters, with the deactivatable and non-deactivatable hydraulic lash adjusters having a same length.
