  • Patent number: 8745866
    Abstract: A method of molding a valve lifter guide includes determining a flow path of injected material in the mold cavity by including a thin walled section in the formed guide. A leading edge of the material flow path forms a dam when crossing a thin walled section in the mold cavity to change a direction of a portion of the leading edge of the material flow path, until the leading edge meets a trailing edge of the material. The valve lifter guide includes a front wall, rear wall, a first radiused end wall, a second radiused end wall, and a bottom surface having an elongated socket. A tab extending from the valve guide support member has a first projection. The valve guide support member is disposed between the engine block and a cylinder head and the first projection is received in an opening of the engine block.

  • Patent number: 8171906
    Abstract: A valve lifter guide mountable in the engine block of an internal combustion engine, the valve lifter guide comprising at least one elongated socket defining a longitudinal axis, the at least one socket dimensioned to receive a valve lifter therein, and at least one tab projecting away from the valve lifter guide along an axis which is non-parallel to the longitudinal axis of the at least one socket. The at least one tab includes a projection thereon which is dimensioned to be received in an opening provided in the engine block. The tab further defines a surface, oriented in a plane generally perpendicular to the orientation of the projection, which is capturable between the engine block and cylinder head.
