After determining that the rata-tat-tat noise coming from the passenger side of my engine is not my timing chain. I think I need to replace the serpentine belt tensioner. Anybody have any experience with this? This is a link to a guys car on youtube that makes the exact same noise. I have replaced the timing chain twice and the last one was with the kit from cloyes that eliminates the timing chain tensioner. That did not fix the noise.https://www.youtube.com/watch?v=8Fg3etZm6r4
