I bought a used 2014 Hyundai Elantra GL (82400kms odo) a week ago and I have been hearing a clicking sound from 1.5 to 2 thousand RPM mark from the engine bay, when I am sitting in the cabin.
Here's a video where I tried to capture the noise.
(Better video available further below)
UPDATE : I found a bunch of YouTube videos talking about the same issues, most of them blaming issues with pistons.
Here's one more video with more clearly audible noise : https://www.youtube.com/watch?v=uRtyPbyomxQ
Is the video's assumption about pistons, correc, tor Could this be something to do with the engine, or timing chain, or any belts, or just lose mounts?
