My motor is making a knocking noise only when warm. I have been searching for answers that the dealer can’t give me. Has anyone determined what this noise is exactly? I see videos with the same noise but no answers. 8k Miles
Thanks

Does it go away with a slight rpm increase? Ive heard many similar noises caused by the belt idler/tensioner pulley. They have a steel spring inside and aluminum case that can make noise when the engine is idling. The power pulses cause minute accelerations on the crank and results in pulsing belt loads.
