Burnt Valve
My 04 Cobra has a slight burble at 1000-1200 RPM that sounds kinda like a burnt valve.
The car has 63000 miles on it. Would it be common to have a burnt valve? Always driven nice. Sorta wonder if a blower motor has a tendency to burn a valve. Sounds like just one exhaust valve to me. |

Sounds like a warped valve as these engines were known to have the back valves warp due to excessive heat. Most people put the cooling mod on the back of the engine to help keep the back cylinders cool.
