First you test the valve body, then you evaluate the results against your own pass/fail standards to determine if repairs are needed. Every shop will have different customers and warranty requirements, and recording results allows you to calculate an average vacuum reading for each bore, then establish a minimum vacuum standard that fits your needs.
Evaluating test results requires establishing your own pass/fail standards in line with your customer's needs and shop warranty requirements.
