Upon totally dissaembling 12 of the 16 lifters from the infamous KB vette i run accross this special lifter... This is very much a crack in the bearing surface of the lifter! Needed to clean out all the shit oil/ metal particles from the disingrated rings.
When looking at it in a magnifying glass you can see it was like ripped apart
HOW THE FUCK does one crack a hydraulic roller on the bearing surface?? Im sure the misadjusted valves and 8K rpms hada little something to do with it! 200 miles on these.
