Silver2018

Thanks for giving your opinion, I already checked the spark plug wires and exhaust manifold bolts. As a last resort, I'll remove the valve cover and check for bad rockers. I really hope it is a noisy injector. I was planning in a future do a DOD/AFM/VVT delete, but not right now

I appreciate your opinion. The truck runs like a dream! I'll try what you've said and see if that's the root cause of the tick.

I have a 2018 Silverado with the l83. When the truck is cold it doesn't have any tick at all and sounds like it should, but when the truck gets at operating temperature, it starts ticking on the passenger side. I checked with a stethoscope and the sound came from cylinder 4 and 8. Right now I'm using 5w30 and the truck has 127k miles, AFM disabled by obd2. Here's a video of the ticking noise after the truck was driven for 30 minutes: https://youtube.com/shorts/jFvwP1aVL84?si=IB-Ry-4wQTKcqq9N Are my lifters bad?
