So I have a 2020 Chevy 1500 3.0 duramax tuned and deleted truck runs great and has a good tuner… tuned from run Vse the guy there really know what they are doing. Anyway I drive about 30 miles a day to work and back and when I’m parked at an idle after driving a ways I hear a loud tick sound under the hood. No codes nothing no check engine light, truck runs great. I opened the hood trying to find the area of the noise I can’t find it. My pipes ( down pipe and exhaust are tight not lose not leaking ) it ticks just one time not multiple in a row.. it does it for about 4 or 5 times them seems to go away. I just let the truck sit for 45 mins started it let it idle and I’m not hearing the tick sound. But if I take it for a nice little ride it appears at an idle again. Starting to worry it’s a lifter or something or maybe I’m just over thinking it any suggestions or information anyone has on this or what they think will be much appreciated
