Hello! First time LS1 owner here. I’ve owned 5 F bodies before, but never an LS1. Just curious, I have a bit of noise at idle, sounds like a lifter, seems to go away after about 2 minutes of driving. Is this any cause for concern or is this a regular LS1 thing? I tried to upload a video but it says it’s too big.
I have some piston slap when cold, which is nothing too concerning, just curious about this lifter how noise.
