lq9 issue Ive got almost almost 3000 miles on rebuild and no issues till a few days ago after about 7 miles pressure dropped to about 25psi bounces and ticks at idle with throttle it goes back to normal. I got to school another mile down the road car sat for about 5 hrs, I started it up and no issues then right before I got home it started acting up again

New oil pump? Was it shimmed correctly? Also my bro had a "tick" in his truck once. Tore down the engine. Did a cam/head swap new valve train. Still had the "tick" after. It was a bad 200k header gasket. Word of advise don't guess and start changing parts or "hoping" for the best. Do research and trouble shoot.
Put a mechanical gauge to verify the problem. Then pull it out and start tearing it down and you just gotta do a post mortem on it one step at a time till you find the smoking gun. I had a 6.0 in my wifes truck spin a cam bearing and do almost exact same thing.
