This is a four-part training program that will show you how to diagnose engine mechanical problems by going in-cylinder. Learn methods to increase the accuracy of your analysis and reduce time spent disassembling by applying in-cylinder pressure testing to your diagnostic routine.
John Thornton will demonstrate step by step pattern analysis and show you how to set-up and use overlays to clarify your captures. The techniques shown help quickly analyze valve sealing issues, valve opening and closing events, crankshaft reluctor problems, tight valves, incorrect cam timing, exhaust path restriction, correct or retarded ignition timing and more. Provided are examples of test results and up-to-date compression specifications for modern engines.
