Any idea what this sound is? New to me 2013
AC is off, sounds like it's coming from both sides of the engine. Sound is present at idle and low speed, it3s either gone at speed or too quiet to hear over the wind. Just bought it and I didn't notice the sound during or after the test drive. When I looked it up, I saw a post about the switch between direct injection and port injection causing chatter. But, no one posted any videos I could compare to. Is this a normal sound? To me, it sounds like the valves need adjustment
