forgot something in the house this morning and left the car in park and heard a weird sound from my hood.
sound like the engine was out of breath.

it did this when the weather was warm and after I drove for a long time and I just thought it was normal or the a/c compressor thing that really didn't bother me and didn't do it that much. but now it is doing it when the engine is cold. wasn't doing it when I got work and engine was warmed up. Sounds like it was coming from inside the engine. No cel and no oil usage and mpg seems the same around 29 city driving.

Sure helps to rev the engine to determine the cause of that rattle type sound. Is the belt tensioner jumping around?

Ha, also need 3D sound, all I can say, it sure doesn't sound right.

Sounds like a top end issue ,cam, lifters, chain, tensioner.
