Rocker Arm Tech Roller Tip
|
Once you lengthen the pushrod and get the roller tip in the center, bolt down the rocker body and rotate the engine a few times. Remove the rocker and observe the valve tip; you’re looking for the narrowest, most center-aligned sweep. If it’s too far to one side or too wide, you’ll need to recheck it. According to a few engine builders we spoke with, typically the sweep will be less than 0.100, but that number can vary depending on engine type and rocker style. View Related Article
