hello everyone i had a engine noise on my silverado and decided to do a tear down to be safe and replace the lifters but it was definately a odd one due to it dissapearing for the most part at 1500 rpm or above. Curious if any of you have experienced this same noise or not and what you did or would have done. Included is the video/link and any input is much appreciated. Thanks 20260101_164008.mp4
