To start, the car is a 2000 z28 m6, hooker lts, ory, LM1, slp lid and smooth bellows. 89k miles.

Since the middle of the summer i have been getting a tick on either cylinder 5 or 7, im pretty sure it's 7 though. Its faint when i start the car, if i keep the rpms under 3k for a trip it isnt all that noticible unless theres something to echo off of next to me. If i bring the rpms up higher on the trip, it becomes much more apparent. If i beat on her a little(rarely), its loud as hell.

One shop told me its most likely a loose rocker or worn pushrod, which i see as a strong possibility. Another shop told me its nothing to worry about, which i dont believe for one second.

Any suggestions as to what to look for? Im going to be pulling the valvecover soon, just waiting for a nice day when i dont have work or class.
