If you already replaced the timing chain components, you shouldn't have to worry about that problem reoccurring, if your oil change intervals (and oil choice) are correct.
If you are nervous, schedule the coolant crossover pipe (and possibly water pump) replacement every X miles, along with flushing/replacing the coolant every X years. I'm still very suspicious that the plastic pipe failures are related to the excessively long coolant change interval, 10 years / 150kmi:

It's mainly the timing chain tensioners and guides. After a certain point, the tensioner doesn't fully extend the piston to push against the guides and causes the loose chain. The chain can stretch too.
Here's a guide that goes through swapping it out. https://www.landroverworld.org/threads/diy-timing-chain.31050/
While you're in there, I'd highly recommend doing everything at once, cooling (pipes, pump, and coolant swap to dexcool), spark plugs, injectors, and (debatable) walnut blasting the valves.
If you can wrench, you can do this. It seems daunting, but it's doable. I took my sweet time in my garage, 4 months from cracking it open, waiting on tools, working sections at a time, waiting on parts, and when it started it was all worth it!
I've been through a lot of trails and terrain. I now have the confidence to take it out and work on it in the field.
Btw... V8 1000% like others said. The scv6 has a turbo lag that I don't care for, nor the eco stop/start, and the worst part is that it has the same or more issues than the v8. Still too new for everyone to see issues, but they're showing up like start/stop battery electrical issues, crank snapping, and probably more.
Did you change the timing chains themselves? If not do you need the cam lock tool to do the tensioners / guides?
I checked my old chains for stretch, comparing it to the new chains, and they were still perfect.
Yes, you'll need and want to cam lock it, because you don't want to mess up timing.
The V6 just has less and feels a little "soft" off bottom. This is partially masked by the 8 speed but not completely. If it really bothers someone there is always the option of a tune an/or pulley which will bring the power back up and then some.
So you did replace the chains as well.
I have a leaking valve cover on the passenger side, and it’s finally getting to be more than a drop on the driveway once in a while. Figure since getting the injectors and valve covers off is the most of the work might as well to the tensioners guides and possibly chains.
