LS2 Fuel Injector Noise...?
When engine is cold I hear a clicking noise upon accelerating, it diminishes as it warms up but only diminishes.
I have an 07 LS2, 19k mi. No engine mods (CAI) run 93 octane only and have used BG, Techron and Zmax fuel additives in the last 6 months.
I was told by the dealer service advisor its the fuel injectors and is common but not a problem.
Anyone?

I hear it too.
My service advisor and his "#1" Corvette engine mech both say it is normal and that it is a very mild piston slap. I've read about it here and everyone seems to think it is normal and a non-issue. I presume that if it gets louder or doesn't stop after warm that it then is an issue. Funny though, I don't remember hearing it during the 1st 2 years of driving it. Hmmm

I am having similar problem with my Lingenfelter engine, 'cept it clicks louder when warmer. Sounds like a single valve tapping. I have posted this on a separate thread, but the topic is similar.

I have the same thing seems to do it from 1800 to 2600 rpm give or take. dealer keeps on blowing me off since themes no codes coming up. I keep saying its mechanical not electronic. They go as far as saying they don’t hear it like I’m an ***. i mean you can miss it! if it is piston slap, then what’s the resolution? I have a bunch of mods I want to do but want to get this cleared up first.

Put a metal stethoscope or screwdriver up to an injector while idling. You can hear them hammer. Not lifters. Sounds like piston slap.
