In this presentation, we will show you how you can assess the mechanical condition of an engine without the stripping of any parts. We'll show you how you can set up, in a matter of seconds, for intake manifold, exhaust, and crankcase pressure testing. We'll describe how the results should look, to help you gain confidence in your measurements. And not only that, we'll introduce some typical faults, such as compression issues so that you can learn the basics of pressure waveform evaluation.
