    2014 Tahoe ticking update

    having trouble troubleshooting a ticking noise… I was told exhaust leak on drivers side (rear stud snapped off inside the head) but I don’t see any soot or feel any air. I picked a stethoscope up and started listening everywhere. I listened to both manifolds, both sound good. Here’s where it...

    Guys I need help figuring out this engine rattle

    Hey guys I think it has come time for my Tahoe for a AFM lifter delete. I think I am having a lifter failure but this sounds different from other videos I've seen. Someone said the pushrod might be out of place causing this sound? What do you think?

    Intermittent lifter tick on cold start

    ‘09 SSV. Has an occasional loud ticking on cold start. Usually goes away in a matter of seconds. Sounds like a collapsed lifter that is stubborn to get pumped back up. Purchased a Range AFM disabler today. I’m hoping if that lifter stays pumped up it won’t get worse. Anybody have good...
