Hi ,
I am thinking of buying a 2010 Jaguar XF R with 54245 miles.
Does anyone know after what mileage (static) the timing chain breaks down ?
I am afraid that I will buy this car and immediately have to replace the timing chain ...
the car cost around 16 k dolars what is a really good price . Jaguar is not really popular car in my country
I would also like to ask if every Jaguar XF R has an R stamp on the dashboard and on the back of the trunk ?
This one is completely devoid of R markings ... Not even air intakes on the bonnet ... But the seller tells me that this is the original with 510 horsepower engine.
First of all the pictured car is not an XFR and the seller is lying to you, the bonnet and bumper are not those of an XFR. I had a 2010 XFR so I know very well what it looks like.
It could possibly be an XF Supercharged though, with the same engine (AJ133SC) but detuned from 510 PS to 495 PS, but even then I believe the XF Supercharged also had bonnet vents with "supercharged" embossed on them. If it does have the AJ133SC it is easy to tune to 600+ PS.
The timing chains on the AJ133 can break down at almost any time but they can also last for 100,000 miles plus, it very much depends on using the correct spec oil and religiously changing it at least twice as often as scheduled.
And it's not really the chains themselves that break down, it's the chain tensioners and guides.
JLR updated the tensioners and guides some time in 2014 to a different and more robust design and they changed the design of the chains at the same time (from 6.35 mm pitch to 8 mm pitch and from 9 links to 3) so you can't update just the tensioners and guides you have to update the chains (and cam sprockets) as well.
Anyway if you really want an XFR and not a lesser model of the early XF I would steer clear of that one.
Agree with Oz. That's not an XFR. It looks like it has the big brakes up front and assuming it is a V8 (?) then it's likely the XF V8 Supercharged. (But check for supercharger...)
The XF V8 SC didn't have bonnet vents, and the front grill and intakes below the headlights look right for that model
It is basically the same car without the body kit. And an almost imperceptible tune difference. So still could be a good buy - but I worry if the seller is mis representing...
50k is pretty low for timing chain issues. But it's a bit hit or miss. And it's a 12 year old luxury car so repairs will be expensive - hopefully you can DIY or are patient and have a good independent mechanic with decent rates?

Based 5.0 SC is detuned to 470 not 495 in the USA …
Yes - lots of reviews when it was launched saw it around 4.3seconds in real life testing. Occasionally a bit quicker but the traction to RWD is probably the limit. XFR seems to run about the same, again suggestion traction is prob the limit. And also highlighting that 470 vs 510hp is a pretty minimal difference in real world driving. I've driven both and cannot tell the difference. Which is why I ended up with the V8 SC as it was a lot better priced when I bought 10 years ago
Note that the 2009 V8 supercharged is a very different engine (4.2L) and meaningfully slower in a 0-60 sprint.
So what did you decide to do? Hopefully you’ve got the car that you’re looking for, take your time and buy a true XFR if that’s your desire don’t settle.
