If checking an engine's ability to Suck, Squeeze, Bang & Blow using a scope and pressure transducers is wrong, then Brin Kline does not want to be right! 

Brin uses this Mechanical Misfire case study to demonstrate some of the details of these testing techniques while helping our viewers analyze the symptoms and waveforms to pinpoint the cause of the concern

Brin; Good morning Sir, and thank you for another great video by Trained by Techs. I'm attaching a Case Study I did on a similar vehicle with a similar Intake Lifter Fault. The case study PDF file has some pictures of the damaged lifter assembly along with some In-Cylinder Waveforms. Keep up the good work, you and the team at Trained by Techs are definitely making a name for yourself.

I hope Brin can answer this one -- in the captures the pressure transducer shows about -2 psi for atmospheric pressure, even though the WPS500 should calibrate itself upon being turned on. What is happening with this WPS500, is it getting old? Other WPS500 captures have the atmospheric pressure dead on at 0psi (see Robert's post above, for example). This issue casts shadow on other numbers in…
