It's not rhythmic, which you would expect if it were some sort of valve train or piston problem. The motor sounds good. I think the first thing I would do is take the valve cover off and see if there's anything loose under there. It could be something metallic just bouncing around in there. It sounds very light, like a small piece of metal. | | |
