Pressure & Vacuum Waveform Analysis
Eliminate headaches by learning how to do Pressure and Vacuum testing to determine the state of health of the engine. Save time by not hooking up your vacuum gauge, taking out spark plugs, or removing components to access testing areas. A picture is worth a thousand words interpret cranking, running, and at cruise compression results through waveforms. Learn the importance of valve timing in the running compression test. Ron Bilyeu also covers vacuum testing to help determine if the engine is running as an efficient pump using a lab scope with pressure transducers. You will be able to perform these tests and interpret the waveforms in 10 minutes or less.
