Abstract: Methods and systems are provided for a cam carrier insert coupled to a cylinder head of an engine. In one example, a system may comprise: a cylinder head with a cam bearing tower; a cam carrier insert positioned in the cylinder head; and a camshaft, the camshaft directly supported by the cam bearing tower and directly supported by the cam carrier insert. By mounting a first portion of the cam shaft to the cam bearing tower and a second portion of the cam shaft on the cam carrier insert, the system may operate deactivatable and non-deactivatable intake or exhaust valves of one or more engine cylinders in the engine. In this way, packaging of engine components within the cylinder head may be improved while promoting better engine performance.
