Default Does this sound normal?

My V6S at idle. Sounds very noisy, like valves or something? Or is that how they all sound? Thanks!

Well... it sounds like some auxiliary component is feeling hard done by. Knackered superchargers sound epic. Which this does not...

Go buy a $20 automotive stethoscope at a car parts store and identify where the sound is coming from.

My V8 sounds like this, maybe not as loud, but your microphone might just be sensitive. I'll use my phone today to recording my engine.

Thanks folks! I was hoping for "naaah, it's fine" but maybe not so much? Yeah, my bro said grab a piece of PVC tubing for the same end result Unhingd.
zmoothg, that would be great, thanks!
Edit - Have had it 4.5 months, approaching 3K mi.

I am not sure if this is normal, but this is about how my engine sounds. If you find its an issue, please let everyone know.

Mine sounds just like that, even after I had the supercharger belt tensioner changed and then the SC torsion isolator / coupler changed, both under warranty. Mine has always sounded like that, before any changes and then after each change. I suspect the dealership did not change either thing, despite worksheets saying they did so.
They are the only JLR dealer within 800 km of me (otherwise I would go elsewhere), I have never bought a car from them, and their service has always been a bit "hoity toity" if you know what I mean.
I'm now resigned to living with a rattly engine, although the rattle does die down a bit once it is warm.

Thanks SinF & Oz! I will sure let y'all know if I come up with anything. Need to do an oil change soon, so will ask then. Don't think I will take it to my dealer, they thought that this noise was fine too so probably wouldn't do anything about the engine noise...

Before I went high tech a couple year ago, I would use a very long screwdriver (with a round handle end for better ear ergonomics).

My wife's LR4 sounded like that this winter for awhile.

Sounds like normal direct injection motor sound to me.

I think there is normal and then there is "normal".
My XFR with very much the same engine, just V8 instead of V6, made nowhere near the racket my F-Type engine makes. Just a mild bit of injector noise, more of a tick than a rattle, which is to be expected on a DI motor, and only detectable with the bonnet (hood) up.

I've done that and used tubing, but a mechanics stethoscope is cheap so sported for one many years ago. You can use the probe to place against parts or you can unscrew it and then use the end to help determine general location.

A great invention. Comes in handy to detect failing components before they leave you stranded.

Thanks to Lance & Steve just went out and bought a mechanic's stethoscope and had a good listen to the engine.
Turns out all I could here was the DI pulsing and the SC whirring, and overall it was pretty quiet, almost no rattle at all. So maybe the dealer did replace one or two parts after all. But this was on a warm/hot engine, I need to perform another test tomorrow morning on a dead cold engine, because it definitely rattles like crazy when cold.
