ABSTRACT:
A valve train module with rocker positioner and non-rotation guide has the rocker positioner and non-rotation guide in the form of a longitudinally extending U-shaped member with lateral outward extending rocker shaft supports adapted to retain a pair of rocker shafts in parallel spaced apart relationship to each other, with each of the rocker shafts pivotably supporting a plurality of rocker arms thereon actuated by hydraulic roller valve lifters operated by an engine driven camshaft for the valves in the cylinder head for a bank of cylinders, the U-shaped member having a base and parallel upright side walls with the base having bolt receiving apertures for its attachment to a cylinder head and each of the walls having at least a plurality of spaced apart pierced openings defined in part by sets of spaced apart inward extending rocker guide flanges to effect the pivotal positioning of an associate rocker arm, the base further having spaced apertures arranged to operatively receive an associate flat sided hydraulic roller valve lifter such that the upright side walls act as a non-rotation guide for the associate hydraulic roller valve lifter.
