My Camaro makes that tick just like that video I watched on here! Trying many things 2 make it go away The Mystic oil, but it realy started right after I got an oil change since I bought it , Also I have the mystery of my coolant dissappearing bout a pint a day if I don't keep an eye on it it will overheat , I just got real nice Duel Exhaust that makes it so mean I really like the car it started 4 me everyday even in the coldest winter we had. I also have the check engine light on and the codes that came up were misfires in the 3rd cylinder , and there is some vey bad heistation feels like the motor fell out or just gave up. Also feels like im losing compression up by the headers on the exhaust ? Just want the power , the motor 2 sound smooth, and 2 keep her cool I want 2 avoid big costly work!
