Properly diagnosing bore wear by vacuum testing valve bodies means no wasted time and money on repairs that aren't needed or aren't working. It's an ideal technique for preventing comebacks and improving the efficiency of your operations.
Learn how easy it is to put vacuum testing to work in your shop by watching these three instructional videos presented by Sonnax Tech Specialist Jim Dial.

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.
