you can hear it around :43sec, i was wondering if yall know what it might be, thanks.
EDIT:Okay guys, today i just noticed it a bit more... i changed the oil putting 5w-30 castrol high mileage... i was looking for the GC and had no luck but i just figured i'd put it on my next oil change but anyways today it sounded a bit louder, i dk why if the car is suppose to take 5-30. what do yall think? piston slap? lifter? oh and i think its coming from the left side if im not mistaking

its really hard to hear, it doesnt sound like a lifter to me, all of the bad lifters i have heard seemed to be way more high pitched, and a definite clicking noise
just from those videos i would think a bad rod bearing, but its hard to hear
could be piston slap, which is what i would say it was.

I had asked at some local guy that works specially on LS1 motor and he said it normally does this at a cold start. Today after changing my oil i left my car running for a good 10 or so minutes and it kept going, so i dk. i put up a new vid for you guys to see whats up
thx

mines making the same noise...i'm leanin towards a rocker arm issue or a lifter bein that it seems to get quiet when the motor is above about 2k. more rpms more oil pressure, less noise i think.
