anyone else run into rattling timing chain noise on 03 cobra engines? the noise will just go away at times, i only have 8800 miles on it, but it is out of warranty on the time. i'm about to take it to the dealership, and want to be prepared. i own my own repair shop and am an ase mastertech, i feel it it the passenger side tensioner, but there is strength in numbers. so other owners with same concern will help me.
