5.7 Hemi
I have a 2020 RAM 1500 Classic SLT (5.7 hemi) with around 47K miles on it that I just bought 4 months ago. I started hearing a ticking noise when accelerating a couple of weeks ago that started quiet and got more noticeable after a few days. I started reading about the 5.7 hemi and found out about the lifter issue (hemi tick) and decided to try what a lot of people suggest and used a high moly content oil. Drained the oil from the dealer and filled it with Royal Purple to give it a shot. While 200 miles or so on the new oil and the ticking seems to have gone but now I hear a different noise...

When I accelerate good and rev up between 3,000 and 4,000 rpms there's a different noise now that is more like a chirping or clicking rather than ticking. It is NOT rhythmic, its more intermittent and random. However, if I am revving around 3-4000 rpms and then shift into neutral and rev the engine up in neutral the noise isn't there. Does anyone have any idea what this could be? Not sure if it's related to the tick or not. Any insight is appreciated.

You should never hear ticking while accelerating, that just aint a good sign. If you can youtube it we can listen?

Did you ever figure out what was going on or did the noise stop?

It is the idler pulley. Take off the serpentine belt. The noise will stop. Change out the idler pulley. The dealer wanted to change out the passengers side head. Told me not to drive my Ram 1500.
