ABSTRACT:
The invention pertains to a guide for roller valve lifters for internal combustion engines which prevents rotation of the valve lifters. The guide is molded of a synthetic polymeric material to define sockets receiving the ends of the valve lifters having flats defined thereon. The sockets of the guide are partially defined by cantilever supported fingers engaging the valve lifter flats, preferably with zero clearance, whereby the guide prevents rotation of the valve lifter about its axis.
