5.3 lifter squeal So I had my fresh rebuilt 5.3 sitting and idling, for about ten minutes, and I walked over to look at the guages, I take note, it's a bit warm, not over 210, oil pressure is at 47-50. I look at then engine and as soon as I made eye contact it starts squealing, so it turn it off call my dad, and start it back up, it does it about 5-10 seconds and stops. I drove it up and down the drive way, and I didn't do it agian. Has anyone else seen this before, they are brand new ZZP lifters and if I look up lifter squeal on youtube, it sounds just like it. Idk what to do, ide hate to waste my new motor, Please any help would be great...
