I have a 2019 silverado 5.3 v8 with about 20,000 miles , I’ve been through 2 push rods , 16 lifters , and a rocker arm. I’ve now blown a hole in the block, I work at a GM dealership in the body shop , I’m no mechanic by any means but from racing all my life I know my way around a car , I do not BEAT on my vehicle, I do not over load or tow over weight , no one including GM can explain why this has happened , I’m just trying to see if anyone has had any other problems like the ones I have had

 

Welcome from Florida. With a hole in the block they should give you a new engine and that should hopefully end your problem.

 

Sometimes over revving can bend push rods. As can jammed lifters.
