Abstract
A cylinder head for an internal combustion engine includes a casting having a number of camshaft support bulkheads. Each of the support bulkheads has a portion of a parent bore bearing for mounting a camshaft. A bulkhead thrust surface is formed in an outer surface of at least one of the support bulkheads. A camshaft is rotatably mounted upon the support bulkheads. The camshaft has at least one thrust bearing member abutting a bulkhead thrust surface which is provided with lubricating oil by means of a radially extending, surface-piercing lubricant distribution channel formed in the bulkhead thrust surface, such that oil flowing in the parent bearing will be caused to be deposited upon the bulkhead thrust surface as well as upon the camshaft thrust surface.
