Thanks. I listened to it with a rod to my ear it sounds like a valve or lifter tap to me

Thanks that makes me feel a little bit better

So should I worry about it ?

So should I have it looked at?

Thanks I've heard that alot.. just worried about it because it's New to me

I bought a 2009 gmc Sierra with a 5.3 vortex engine with 51000 original miles on it. It has a tapping noise at start up.quiets down after engine warms.Is this normal or do I need to have it looked at?
