LIFTER BORE GO-NOGO
An expedient method of checking and verifying both lifter bore wear and size is with a “go- nogo” gauge. This is not meant to replace the use of a dial bore gauge, just as a quick check. They are easily machined on a lathe. They can be machined from any hard material. I prefer stainless steel due to the material’s oxidation resistance. I have made a number of these in specific sizes for some customers as well.
