my 94 camaro rs is makin a clickin noise. i put flowmasters on it and could only get 1 of the 2 bolts back into the cat. it runs fine but i know i have an exaust leak. i put some radiator stop leak in it and the next day the **** thing was makin a clickin noise. it started that morning when i first started it but stoped w/in 15 seconds. so i didnt think anything of it. i drove around all day. and that night when i was goin to run to the store, there was the clickin. i waited and it didnt stop. so i put some sea foam in my oil( thinkin 1 of my valves was stickin) didnt work.
what could be wrong?
i live in plano off 121 and coit, and if someone could come by and look at it and mayb tell me whats wrong or something that would be great.
