    Wrench Tales #5: Chris Arriazola

    June 19, 2024
    Brandon and Chris use pressure waveforms to accurately pinpoint a bent intake valve!

    We’re back for the latest episode of Wrench Tales with Motor Age’s Technical Editor, Brandon Steckler. This time with his great friend and former student of Brandon’s, Chris Arriazola of Pride and Joy Auto in Amarillo, TX.

    Chris was faced with a 2019 Chevrolet Camaro SS V8 that experienced a strange rhythmic ticking noise from the valve train and a misfire from one of the cylinders. Through previous experience, Chris believed it to be caused by a faulty/collapsed AFM intake lifter. Using only his lab scope, hi-amp probe, pressure transducer, and Event Timing Overlays (from The Driveability Guys), Chris quickly uncovered an engine mechanical fault.

    Reaching out to Brandon with the captured data in hand, together they tag-teamed the analysis. Through a multi-trace lab scope capture, they were able to derive that there was nothing wrong with the intake lifter but definitely an issue with the #8 cylinder’s intake valve sealing properly.

    Stick with Brandon and Chris as they discuss the analytical process and what the testing offered for Chris regarding his confidence in disassembling the engine to pinpoint the problem. The in-depth discussion can only be found here on Wrench Tales!
