Chirping noise possibly lifter issue?

2012 Ram 1500 2wd Hemi
So the last couple weeks I have been to the bank twice and heard a bird chirping while sitting in the drive thru next to the brick building. First time I thought it was just a damn bird up under the canopy/overhang, but I heard the same noise yesterday and figured I better check out the belt and pulleys after I got home. Away from the building it isn't audible either in the truck or standing outside of it, but after the hood is up and listening then I can hear it. It is very intermittent and obviously not very loud. Sprayed water on the belt where I could reach from above without a change. But to be honest I couldn't get the water sprayed hardly anywhere with the shroud in the way and the fan blowing it away. The belt has some signs of wear so will be replacing that shortly, while also checking the pulleys with the belt off. A couple years ago I had replaced the belt, idler and tensioner pulleys on my previous '04 Ram, but that was a different noise like a whine that got louder with increasing RPMs.

I watched some Ram belt/pulley noise youtube videos and came across some people with the same chirping noise, although a bit louder it appears, and some are claiming after replacing the belt and pulleys that it ended up being the lifters. They go on to claim that it can lead to lifter and cam failure due to the cheap plastic guides, some dealerships are now telling them this, etc. These comments are all within the past few weeks to a year. So it's possible that this is a major issue now cropping up on '12 and '13 models, or it's entirely possible these people are full of ****. Anyone heard of such a problem with our trucks? I searched but couldn't find anything more about it.

I traded in a perfectly good '04 for my '12 simply due to mileage and the number of miles I put on a truck, I'll be pissed if this leads to a major issue. Link is below with the lifter comments,

I heard that on my 3rd gen. Thought it was the tensioner and replaced it. Noise was still there. Trying to track it down, I believe it's coming from the alt. Checked the bearing for play and found none. Was still trying to track it down, but it went away. It's been a couple months now and it hasn't come back that I've noticed. There have been some lifter problem's in the 4th gen. Hopefully not a major problem just a annoying one. Try taking the belt off and see if the noise goes away with it running. Let us know what you find it.

Take the belt off the truck and check again that noise sounds pretty solid like tap no really a squeak to me more of a sliding tick type noise. Remove belt and see if the noise is gone if it is then it’s likelyon the belt or accessory setup if still there get to digging in sadly

The link is not my truck, or video. My truck makes a very similar sound but not as loud and much more intermittent.

I have a new belt on order and will remove the old belt this weekend, and start the engine before the new belt goes on. I'll update when I know more.

I didn't know there was an issue with 4th gen lifters. I am definitely not happy to hear about it.

I researched a little more about the lifter problems. It seems to be narrowed down to the 2011 trucks, specifically cylinder #5, and after many more miles than my current 99k. So I feel a little better and much more optimistic haha!

My truck does have the tick from the right side manifold. I haven't dug into yet, but I'm 90% sure it's just from the manifold/studs and not the drivetrain. It started up towards end of last winter. Always goes away after the truck warms up, maybe a minute if that.

Even though it seems to be narrowed down to the 2011 trucks, any '09+ has the potential. It appears to start with a very noticeable tick, which some Hemi's are notorious for, but eventually the CEL comes on especially when under load such as passing another vehicle on the highway. The code reads as a cylinder misfire, which leads to the lifter/cam failure. Some also mention their trucks shake real bad when the CEL comes on under acceleration. The problem doesn't seem to be related to MDS as it has happened on non MDS engines.
I don't have any of those issues so I feel a little better and much more optimistic. Not that this should matter but I always turn off the MDS cause it annoys the hell out me and I get better mpg without it active.
If the belt/pulleys is not my chirp issue then I'll send an oil analysis as that seems to be the best method to track down an internal problem.

I have used either Mobil 1 or Castrol Syntec on this truck, same as my previous trucks. Change every 10K with Wix or Mopar filter. Oil always looks very good.

I removed the belt, the chirping noise is still there. Any ideas?

Does the misfire identify the cylinder?

I don't have a CEL. My earlier posts were simply explaining the issues I found from others with the lifter problem. My motor seems fine other than the tick on cold start and now this chirping noise. I have assumed the cold start ticking is simply from broken manifold studs as that is very common. But now I'm second guessing and need to dig into it more. Hopefully the ticking is just the manifold studs and chirp is hopefully an exhaust issue as well. Or this is all potentially leading to the lifter failure.

The chirp is very likely a roller lifter dragging on the camshaft rather than rolling on it. I suggest diggin into the asap as to avoid any real big issues
