LR4 5.0 V8 - recent timing chain service with 4 new camshaft adjusters - still seems somewhat noisy??

I think it’s hard to judge actual volume from a video and my seem louder than it is? My 2011 sounds similar to your recording at times, but varies somewhat and isn’t what I would call loud. I think I just accept it’s a bit noisier engine than the LX470 I had.. ok, way noisier but with 100 more horses and slightly better fuel economy.

When I bought mine used, it was that kind of noisy at 96,000 miles; however, as I used the recommended Castrol 5w20, it somehow was quieter after 2 oil changes at 1000 miles interval so far. I plan to do oil changes every 5000 miles.

Injectors make a hi-pitch ticking noise here. Other sounds seem to be coming from timing or belt driven accessory

My 2010 is quieter than that with OG chains and guides. I'm surprised you heard a sound from a cam adjuster over the fuel injectors.. to that point, my fuel injectors sounded same before and after brand new ones at 110,000 miles. They don't sound as deep as yours . Higher clicking noise like someone else suggested. I think you should take it back to the shop as other LR4s I've heard (like on other videos) don't sound like that.

The first time I did my timing chain, I had the same noise. If you look at the live data from a code reader (Gap IID Tool) for intake camshaft degree (something like that). Normally it should be around 100 (+/-30) degrees, if it's in the 200 (+/-30) degrees then it's off by just that much and you don't have enough tension even though the markers are in the correct placement.

After a few reps of doing the timing chain myself, I got it down packed. The markers are aligned perfectly AND there was zero play between the sprockets. So, I went from the sound you're producing to "quiet".
