Worn Down Engines Cam Thrust Button
|
Installation of a cam thrust button is recommended when switching from a flat-tappet cam to a retro-roller cam. In a flat-tappet Corvette engine, the taper of the cam lobe exerts rearward pressure on the cam, as does the distributor gear that drives the oil pump. Comp Cams offers stamped-steel covers that look original, but are reinforced inside for the thrust button. View Related Article
