Hi Scotty I wrote you before telling you about a rattling noise coming from intake plenum or somewhere else from there. It only does it when is on drive or 1 2 3 speed. It not does it when is on parking or neutral. I don’t know what it is. Could you help me? I leave you a link for the video on YouTuBe I really need your help. Thanks in advance

first, take off all fan belts and pray the noise goes away AND it's a bad alternator or something there. If not, that is serious internal engine wear, like worn cams or valves inside the engine. If so, big money there, you might try a heavier weight oil and sell if fast if noise quiets down for a while

the sound only does it when it accelerates to a certain speed. about 1800 rpm. in fact it was quite difficult to achieve. when I accelerate it more or less the sound disappears
