EFFECTS OF ENGINE OIL SUPPLY ON ROCKER ARM AND BALL WEAR

Recent studies have shown that after starting an engine at sub-zero temperatures, more than 6 min elapsed before oil reached all of the rocker arm assemblies of a V-8 engine. Since this could have an adverse effect on rocker arm and ball wear, the effects of intermittent and zero oil flow on rocker arm and ball wear were investigated. The metallurgy of the rocker balls influenced ball wear greatly. In addition, the impregnant used in sintered iron alloy balls influenced wear. /GMRL/
