Abstract
An injector sleeve for a cylinder head may include a lower portion, a middle portion, and an upper portion. The upper portion may have a maximum thickness along at least a portion of a length thereof, and a groove on an inner surface of the injector sleeve. The groove may have an upper planar surface that is normal to a longitudinal axis of the injector sleeve. A related method of removing an injector sleeve from a cylinder head may include inserting a removal tool into the injector sleeve, within the cylinder head, by a predetermined depth, engaging a surface of the removal tool with an upper planar surface of a groove on an inner surface of an upper portion of the injector sleeve, and pulling the removal tool outward from the cylinder head, thereby removing the injector sleeve from the cylinder head.
