XFR Engine noise

XFR Engine noise
My car makes this noise, and it isn't the injectors. I can hear it more on the left side(facing the motor).
I used my auto stethoscope and the coupler isn't making noise or the water pump . I can hear it the best when I put it up on the oil filter cap/ housing.
The noise gets faint or goes away at higher RPMS.
This isn't my video, but that's the noise I'm hearing. Thoughts?? 2013 w/ 33k miles, and oil changed every 5k miles. The oil filter doesn't have any metallic bits.

That sounds like a rocker or lifter issue as it's very rhythmic. But it could just be normal cam lope. AJ133SC engines are noisy, if as you say you have no metal in the oil, or oil pressure problems I'd just chalk it up to that. You could try a different brand of oil.

Coming from the Merc E63 with 6.2 liter engine with lots of cam noise- All the Merc techs said that it was "somewhat normal." Is this the same case as in the OPs video?

Never ... I do all my own maintenance and never had the low oil light come on. I pump out the oil and it usually about 6 qts out.
If it was that... wouldn't it increase with the rpm vs going away? Above 1500rpm it's fine.
Ps. I agree, as I bought a jeep with that issue. But it would increase with the rpms.

It's all of the above.
I removed some stuff today and narrowed down the sound.
It's one of the upper tensioners, and the supercharger isolator/coupler . Pondering a trade in or fixing it.
No CEL, so it's must be the ratcheting part... bc hydraulics kick in at higher rpm.

5.0 engines don't have upper tensioners. I've done quite a few timing chains.
I'm also sure your s/c isolater is bad also. 90% of the 5.0 s/c timimng chains i've done need s/c isolaters.

I do not hear anything from the oil pan.

hope you have extended warranty. sorry to tell you, but that sure sounds like timing chains..
here's another video of a timing chain noise

I drained the oil from the drain plug and found a bunch of tiny plastic bits. Most tiny specs, but 2 larger pieces.

There are some intake differences, and the water pump is definitely different, but the core is almost identical.

The Ford 5.0 "Coyote" is based off of the 4.6L modular motors.
It has a bore and stroke of 92.2mm (3.629 in) and 92.7mm (3.649 in)
The Jaguar 5.0 AJ-V8 III (AJ133) is based off of the other AJ-V8 motors.
It has a bore and stroke of 92.5 mm (3.6 in) and 93.00 mm (3.7 in)
Also the AJ is direct injected, the Coyote is not.
I'm pretty sure they aren't related at all ... but I'm just going off of information I found online, such as yourself.
