Abstract:
A hybrid valve lifter guide formed of metal and nonmetallic material for maintaining the angular position of a reciprocable valve lifter having a circumferential surface with at least one alignment flat. The guide includes a metal guide body having a longitudinal guide wall with at least one guide opening through the wall. The guide opening is adapted to receive a valve lifter. A nonmetallic insert is retained by the body adjacent the guide opening to engage at least one alignment flat of the valve lifter received in the guide opening to substantially maintain the angular position of the valve lifter and dampen angular oscillation of the lifter during engine operation.
