Need some help from the experts to identify this ticking on a '16 LR4

[djkaosone]

There's 2 distinct sounds, at the beginning you hear both at the same time, and at the 0:24 second mark you hear the lighter ticking sound (injectors). I'm pretty sure the other sound is the timing chain slop. Tell your buddy not to drive it and get the timing chains done before he needs a new engine.

It's my understanding that the timing chain issues were in the V8 (and were resolved before the V8 ended production in the 2013 model year) and are not appearing in the V6.

The OP has a 2016 which is a V6.

Not saying it could not be a timing chain issue - if the oil changes were not sufficient pretty much anything can go wonkers in there...

I have 2015 V6 and timing chains puked on me. Oil changes were @ 5000 miles.
130,000 miles

The '14 and up SCV6 3.0s have the updated timing chain guides, BUT it's still an issue. At one point "they" were reengineering a new design, but gave up on it and just decided it was cheaper to do a recall. If you also look at it this way, the recall were for '12-'14 and the '14s had the newer timing chain guides.

But we all agree, this are noisy engines... unless you perform a very major overhaul.

Actually, I don't mind the noise any longer... sounds like a battle worn 4X4 up for the next challenge.

I have the same type of sounds on my 2 V6's. I am not concerned with mine - but they are not as pronounced as yours.
But I would not not be concerned about yours either - but I am no expert....
Sounds like fuel injectors.

Just a note of advice on replacing fuel injectors - I replaced mine on the 2002 Nissan and I cheaped out buying less expensive ones - needed to replace 2 of the 6 within a couple of months.
IF you do the injectors on your Rover, I would only go with OEM.

As far are reliable dealers in your general area - I know it's a full day away, but we have had excellent results from the Rover dealership in Rochester, NY.

At 86K miles I would be immediately giving the attention to "The Crossover Project"

He already did all the coolant hoses, but IDK if that included the crossover pipes or not. The service receipt didnt line item list the individual parts. If I get the car I was planning on doing a refresh before 100K for a bunch of things, so I'd have my mechanic check on those and if they didn't look new I will plan to get them replaced.

Generally sounds like my engine as well. The one other noise that pops up on the supercharged engine is the supercharger coupler (aka isolator). It’s a spring loaded coupler that tends to fail and can cause a rattle. Usually not an urgent issue, but it’s an easy fix while doing the coolant crossovers (which is a must-do if it hasn’t already been done).

I was already thinking of refreshing the charger at around 100K, along with new plugs, belts, tensioners, etc. But I do have a question, is replacing the oil and the coupler really all that's needed, or should I go ahead and get a full rebuild with new scroll bearings as well? If I go that route, and my mechanic is already that far in... I might as well tell him to pop the valve covers to check the tension. He'll already be most of the way there, and going a bit further to do the chains at the same time if its needed wont be as hurtful to the wallet as if it was its own job.

Agreed about the SC coupler. I changed mine at about 45K miles - already signs of wear on the shaft from coupler failure - not of concern at that time - glad I caught it.

What I dont understand about the replacement couplers is why they arent just solid. The ones I've seen look like they'd snap pretty easily and have tons of space in them where cracks could form and plenty of room for it to deform. (pictured in this listing) Why aren't they just a solid block with the appropriate holes drilled into them? Seems like a solid piece of poly (like what's used for performance suspension bushings) with the correct spacing for the holes would be way more resilient than the "Upgraded Eaton Couplers" I've seen Jag tuning forums reference.

I hear all sorts of sounds and I'm not able to distinguish them because I dont know the quirks of how these engines are supposed to sound. I'm going to try to dig out my stethoscope this weekend and see if I can find a general region where the noise is coming from.

It kinda seems like luck of the draw, there's some early cars with >200k on original chains and they havent had a problem... other people talk about having later models and them blowing up early. I cant make heads or tails of what I should expect.

That sucks.

If you also look at it this way, the recall were for '12-'14 and the '14s had the newer timing chain guides.

its also possible the early run of the newer style had issues... or JRL included them in the recall as a CYA in case there were problems. Kinda hard to know what JRL was thinking with this thing.

But we all agree, this are noisy engines... unless you perform a very major overhaul.

I dont mind a noisy engine, as long as its a good noisy and not a bad noisy. lol

The SC aftermarket couplers from SCOL are excellent quality and fit very tightly.
A solid block does not necessarily distribute applied forces as well as a designed part.

The entire SC oil change and coupler replacement is a section in this video - all part numbers are in the video.
See the index at the beginning.

(It's also great for your insomnia !)

Thanks for all the information and advice.

I've decided to bite the bullet and get the car. After deciding that I'm going to go ahead and get the timing chains down we negotiated and price and I'm now planning out getting that done.

However I've stumbled upon a fun conundrum I didn't expect... finding the list of correct parts may be a bit more difficult than I expected.

On the Lukcy8llc site, they have a kit for the 14-16 LR4
Which in the parts list includes the part number: LR087162
But when I look that up at the various dealership parts sites, they say its not compatible with my vehicle, and that the correct part is: LR052911

And since that's a completely different number, its unlikely to simply be a typo. So... does anyone know if the rest of the parts numbers on the Lucky8 site are correct?

Also because the internet is such a "reliable" source of information at times... I'm reading contradictory information on if the Engine Timing Camshaft Sprocket LR060395 & LR060396 need to be replaced as well. Same with the Crankshaft Gear LR072611 & Crankshaft Gear LR072638

I find that the folks at Land Rover Palm Beach on-line parts are wizards in locating part numbers.
Palm Beach Rover is also a reliable vendor - more expensive than some - but parts are properly packaged and have always arrived in good condition.

That particular "not compatible" message comes from the system that all Rover dealerships use for on-line parts - it is not unusual for the system to say "not compatible" and the part be just fine.
But I always double check that with a real human....
