Shops quote $7,500–$11,000 for this one, and the quote usually isn't the ripoff, the job really is that big. Here's what's actually failing, what the correct repair involves, and the honest part: this is not a job I do in a driveway.
The 5.0 supercharged V8 in these Range Rovers uses hydraulic timing chain tensioners that hold pressure with engine oil. As the engines age, the tensioners bleed down overnight, so on cold start the chains run slack for the first seconds, that's the rattle you hear before oil pressure pumps the tensioners back up. Every one of those slack starts lets the chain slap against its nylon guides, and the guides, brittle from years of heat cycles, start cracking and shedding fragments into the sump.
Once guide material is breaking off, the chain has nothing keeping it tracked. Cam timing wanders, the ECU sees it and logs correlation codes P0016, P0017, and P0020, and the rattle stops being a cold-start quirk and shows up under load. The end of this story is well documented on these trucks: the chain jumps teeth or a guide jams the works, the engine stalls, and it doesn't restart because the valves and pistons have met.
The proper repair is everything at once: chains, every tensioner, every guide, and the crank and cam sprocket hardware the factory procedure calls for. It's a deep job, the front of the engine comes apart, and dealer books put it at 20–30 hours, which is why their quotes run $7,500–$11,000. Doing it before a guide fails is the difference between a big timing job and a dead engine.

Timing Chain, Tensioners & Guides Replacement is on my published list of jobs I turn down. It needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. That list is public on my trust page. I'd rather lose the job than learn it on your engine, and you should be suspicious of anyone who says yes to this over the phone.
So here's what I can genuinely do for you, holding a $7,500–$11,000 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $7,500–$11,000, have someone independent confirm that's actually what's wrong. This is a diagnosis, not the repair, no hoist, no lift, nothing comes apart. I scan it, test it, look at it with you, and tell you straight whether their diagnosis holds up. If it does, I say so and you go pay them with confidence.
Book the second opinion →At $7,500–$11,000 on a car that might be worth not much more, plenty of people replace instead of repair, that's a completely reasonable call. If that's where you're heading, get the next car measured before you hand over money: 150 published points, at the seller's location, written report the same day.
Book a pre-purchase inspection →Tell me what you've been quoted and what the car is doing. $100–$250 flat, at your location, and you get a straight answer either way.

Not so you can do it yourself, so you can tell whether the shop quoting you understands the job:
That's the job. It's why this one belongs on a hoist instead of in a driveway, and it's why $7,500–$11,000 usually isn't a ripoff, it's a big repair honestly priced. What's worth checking is whether that's really what your car needs.
Get the diagnosis confirmed firstPlain version: Timing Chain, Tensioners & Guides Replacement needs equipment a driveway doesn't have, a hoist to get under it properly, a press or a machine shop for the parts that come out, and a controlled space for an engine or gearbox that's in pieces for days. I work out of driveways with hand tools. That's not false modesty, it's the published limit of what I take on, and it's listed on my trust page alongside the warranty.
What that means for you: this page is here to tell you what's failing and what it should cost, so you walk into a shop knowing the job instead of nodding at a number. And if you want that number checked before you pay it, that part I can do, $100–$250 flat, at your location.
A bled-down tensioner is annoying; a shattered guide is terminal. Once the guides start shedding, every cold start is a gamble on whether the chain stays on its sprockets. The documented failure mode on these 5.0s is exactly what the symptom list says, the truck stalls and never restarts, because jumped timing on an interference V8 means bent valves at minimum and often piston damage. At that point the timing job becomes an engine replacement on a Range Rover, which is one of the most expensive propositions in the used-car world. The cold rattle is the warning. It does not get better on its own.
No, and any shop offering that is setting you up. The guides are the part that actually kills these engines, and they're brittle on every truck old enough to rattle. The labour to reach the tensioners and the guides is identical; leaving aged nylon in there wastes the entire job. Chains, tensioners, guides, all of it, once.
That one second is the window where this repair is still 'just' a timing job. The progression, longer rattle, rattle under load, cam codes, jumped chain, can play out over months or over one bad morning; there's no reliable way to predict it. With codes P0016/P0017/P0020 present, you're already in the late chapters. We'd rather quote you a timing job than condemn an engine.
No. Timing Chain, Tensioners & Guides Replacement is on my published list of jobs I turn down, it needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. I'd rather lose the job than learn it on your engine.
Two things, and both are real. A second-opinion diagnostic at your car, $100–$250 flat, at your location, so somebody independent confirms that's actually what's wrong before you commit to a $7,500–$11,000 repair. And if you're weighing replacing the car instead of fixing it, a pre-purchase inspection on the replacement, $149–$399 flat, at the seller's location.
Because the useful part isn't the wrench. It's knowing what's actually failing, what the correct repair involves, and that shops quote $7,500–$11,000 for it, so you walk in knowing the job instead of nodding at a number. If you want that number checked before you pay it, that part I can do.
