Abstract:
1. A cylinder head assembly comprising: a first member defining a first port for communication with a first cylinder in an engine block and a second port for communication with a second cylinder in the engine block, the first and second cylinders each having a center that lie on a longitudinal line; and a second member coupled to the first member, the second member defining a longitudinally extending portion located on a first lateral half of the first member completely offset from the longitudinal line, the longitudinally extending portion having a surface including a first oil supply region that defines a first control passage between the first member and the longitudinally extending portion of the second member and a second oil supply region that defines a second control passage between the first member and the longitudinally extending portion of the second member, the first and second control passages being completely offset from the longitudinal line, and the surface of the second member defining a wall separating the first oil supply region from the second oil supply region and thereby isolating the first control passage from the second control passage, wherein the longitudinally extending portion of the second member defines a first lash adjuster housing intersecting the first control passage and a second lash adjuster housing intersecting the second control passage.
