Hey guys, got my 2007 TBSS with 21,000 miles. Sounds like lifters are ticking at start up? Should I be scared? Is this common?:dunno:

It's common. Mine had ticking lifters from day one and I bought it new. I replaced them with ls-7 lifters before I sold it and the ticking was gone. Ran a little faster at the track to fwiw...

Yep...it's common. My ls2 GTO did it the day it left the dealership and was still doing it when I traded it on my TBSS five years later. The TBSS does the same thing.

I've been noticing a ticking noise lately... not sure where it's coming from though? How do y'all know it's your lifters making that noise? :dunno:

Thanks guys, had me scared for a minute. It has a little bit of rattle while running, sounds louder near the back. It's not the injectors, not real worried about it. Just gettin ready to mod it and don't wanna start if it needs TLC.

Damn I just did this. Guess I should have read down further before starting my 4th of july fireworks early.
