Abstract
A bearing housing, or integrated turbocharger housing, with the oil, and optionally air and water galleries, included as as-cast features, thereby avoiding the problems, design limitations and expense associated with conventional post-casting machining. The method of casting preferably uses lost foam casting, or a technique similar to lost foam casting but in which a ceramic shell is formed on the foam form prior to metal casting, but can use any of a variety of casting techniques or a combination of two or more techniques.
