@redwhitekat The problem is a temperature gauge that only moves once you are overheating already, and this is not unique to LR that is pretty much all manufacturers thanks to stupid owners. You know the ones who freak out because a gauge moves.
Really they do not overheat that much, but they run way too close to temps where it becomes a problem so you do not have a lot headroom once things go south. Ideally you want to keep an aluminum head under 220F degrees, so you look at the stock thermostat starts to open at 179 and is fully open at 204 with AC fan helping if you hit 212. If everything is is on good shape you should run between 204 and around 215 with that setup,but that only leaves 5 degrees to 220 and 15 to 230 - beyond 230 the odds of you having issues from overheat are very high. hit 240 and it is almost 100%.

my 03 when I bought it had the stock tstat, it was at 115,000 kms and temperatures ranged from 205-225 and it was always serviced by Land Rover
when I bought it and drove for about 45 min I began to hear ticking, that was my liners loosing and banging and moving
how long would that engine last if I didn’t replaced the stat so it now runs mostly below 200. No more ticking

I belive sleeves slip, and originally thought my 04 had.
Even if 03/04 can't slip down, they can move up.
After replacing an oil pump that had 3 clean through cracks, and new lifters, I pinned all 8 liners...and it still ticked after it warmed up, even though it ran great.
After pulling the heads, there was no signs that the sleeves had been moving up prior to pinning, as there were no impressions on the bottoms of the head gaskets.
The cam, cam bearings, rod and main bearings All had noticeable wear, and were the problem.
Which was kind of suprising for a smooth and strong running engine with 122k miles on it. But it had head gaskets done at some point, so likely had been overheated.
I swear the all aluminum engine resonates the sound differently than cast iron does. Otherwise the obvious loud ticking would've been more of a knock. But, the pistons, cylinders, rod and main journals All measured in spec.
As I've mentioned too, my 4.6 decided to leak coolant between the sleeves and block in 3 cylinders, after rebuilding, while cranking, which just seems to be a quality issue.
