You should hear my sisters 4.8 V8 silverado, it rattles really bad, but only does it at idle, can't tell what it is almost sounds like a rod knock. Yours almost sounds like rocker noise to me.
Some motors and almost all LS motors have a certain amount of piston slap ! if it dont go away after the engine is up to temp then it might be something more serious
just beccause they call it a GTO doesn't mean it deserved the name. What an embarrasing representation of what was one of the coolest cars ever made. All you have is a sported out grand am/ family car. Sorry bout the slap though.
I can totally appreciate that everyone has their own opinion, it's what makes the world go 'round. That said, opinions are best when they are backed by knowledge which, unfortunately, yours are not. The original GTO was a $296 option on the Pontiac Tempest, which was basically what? That's right, a family car. And to your point that it is a sported out GrandAm. The modern GTO is sourced from GMs Aussie Division, Holden (Monaro, BMW competitor) then add the 400HP LS2. Eats mustangs for lunch :)
@jkalisz01 right on brother! i have a 2006 GTO and a 2004 grand am and they are no where near alike! if i feel like drivig around bangin on mustangs and hondas i drive my gto when picking up the family i drive the grand am
this could be that one of your pistons is cracked or broke a peace of it and its floting aronud in the cylinder causing that noice. the only way to find out is to pull the heads off & examine the pistons. my buddy blew cylinder 5 & 7, but it was on spray.
Does it do it when you accelerate? My Charger R/T has piston slap and you can hear mostly when I accelerate. Does anyone know how much it is to fix piston slap?
i hear the same on my 05. took it to dealer and was told this is normal. makes piston slap noise only when cold. this is to allow for expansion when it heats up.
Sounds like top end Noise to me.

Did the noise go away when the engine warmed up? Did you ever figure out what the problem was?

I don't hear anything. Piston slap makes it sound like a diesel engine, is that what you are hearing?

Make sure your exhaust and intake manifold are tight.

Yes , that is piston slap . Although many vehicles can have piston slap ,and not necissarily a problem , General
Motors are worse than others. High spec engines have no piston slap , that is why i do'nt buy GM vehicles.

complete and total rebuild.
source: rebuilding my motor, to fix several problems. including piston slap and GM's famous lower manifold gasket leak on the 3100 series.
if i couldn't turn a wrench, and if it were cheaper i would buy a different car. but that's just buying someone else's problems.

Don't sound like Piston Slap. The one way you can tell if It sounds like a diesel Engine.
