Just heard back from the dealer after taking my camaro m6 2SS in for a tick/rattle noise on acceleration. I thought it was a loose heat shield or something else from front of the car. Ended up being 4 bad lifters and a valve? Lady who called me didn't go to in depth but was all covered under warranty. Car just hit 6k miles
It honestly didn't sound that bad and was hardly noticeable with radio on. This car is my sunny day weekend car and not driven anyway out the norm of a v8 sports car. Just hope someone else reading this with similar issue just plays it safe and takes their car in to get checked out.
