Abstract
A method and apparatus for developing a test for determining if an engine has oil seal leaks. The engine is charged with a predetermined pressure of air and monitored by a leak tester. A digital valve is set to provide a certain leak rate based upon signals received from a digital valve controller. Thereafter, based upon signals received from a PC and a main control unit, a variety of trials are completed. The results and programs are stored in the PC. Results of the trials allow an optimized testing program to be selected that would be best suited for use on a manufacturing assembly line.
