LIFTER BORE STANDARDS
To check lifter bores for finish, burrs or obstruction, I made tools by removing the plunger and internal parts from some lifters. I have a set of various “empty” lifters, specific to application. You can stick the lifter on the end of your finger then slide it, with twisting motion, in and out of the lifter bore. If it sticks, or does not move freely, I deburr and ball hone the bore. It is a fast, easy way to check lifter bores that may prevent problems after assembly.
