I am curious to see how many 5.0 supercharged engines are past the 100K mark?

My XFR is a daily driver and I am adding miles faster than I thought I would.

Any high(er) mileage cars out there?

Andrew

We recently purchased a 2012 XJL with the supercharged 5.0 L with about 45,000 miles, which I considered high for a SC engine just two years old. I'll be interested in seeing future comments on this thread. According to the carfax, the engine did have the water pump replaced at about 24,000 miles. We also had a 2009 XF with the NA 4.2 L engine that had 60,000 plus miles on it when we traded it. Looking forward to more comments.

Bought mine with 52k, but it had all of the following done as verified by Car Fax, Anaheim Hills Jag-Rang Rov and Its priv. owner as I found his contact info in the glovebox when I bought the car?
WP replaced
DIFF overhauled
SC rebuilt by a local Eaton certified shop with a performance bearing upgrade.
all 4 brake rotors replaced.

These things where done after 42K it now has 54K. So yes I have a 2010.1..lol

Timing chain tensioners on the 5.0 liter engine are a problem. You will hear a noise at idle as well as have an intermittent ck engine light. I forgot what the code is but will update this post when I get it.

Timing chain tensioners, water pump, and oxygen sensors were all issues with high mileage no matter how well maintained, and are all crazy expensive especially the timing chain.

The XFR may be the best overall modern Jaguar in the last 50 years since the E-Type. Yup, I said it.

The car had enormous poise and balance. I'm partial to the 2010 as it was the best value and had the originally designed look that was more unique, and drew more heritage cues serving as a perfect "bridge" car between the old and new Jaguar. The adaptive cruise control was standard, paddles were active in Drive mode, grill was chrome, and the gauges and switch gear were silver which I thought was more unique.

I now have an F-Type R, and while it is cool, the XFR was more of an overall package with no limitations at 90% of the performance. Truly special. I miss it....

I've done all of my own out of warranty work for years, so I am somewhat mechanical.

I'd like to hear more about the tensioners. When are they failing? Sounds like you might get some warning?

Thanks,

Andrew

You're lucky that you have that kind of "know how" and time.....it's a typical occurrence over 100,000 miles and it will throw a pending code that the cam timing is off....it may or may not throw a permanent code that would trigger the check engine light.....

A ‘rattle’ / ‘click’ noise may be heard from the front of the engine. The noise may be more pronounced when the engine is at idle speed. You may also get a check engine light for camshaft to crankshaft correlation.

Yes...that is true....

I don't know your source of information, but I have seen failures below 30,000 miles.

Interesting. Hard to find much here on the 5.0 and tensioners.
Either failure or replacement, much less DIY replacement. Though there is a fair amount for the 4.2.

And no one, yet, has claimed to have over 100K miles.

I probably should have done a poll...

Is the timing chain also an issue in the NA version of the 5.0?

Please point to anyone having tensioner issues with the 5.0L?? This list has no one having that problem.

The 4.2L had no problems as by that time Jaguar had revised them three times on the 4.0L which DOES have tensioner problem.

Yes both supercharged & non supercharged engines.

Most people with newer Jaguar & Land Rovers don't post on forums. Why don't you ask your local Jaguar/Land Rover dealer. They should be able to confirm what I am saying.

Yes...it happens on the 5.0L engine as well, and this was directly communicated by my dealer who is very good.

John:
what is the failure mode for the timing chains? Are they similar to the AJ26 problems? Are both the primary and secondary chains a problem, or is it just the tensioners.
Thank you for your insight!

Also lets not panic everyone with pulling off their engine covers an hearing a "tick" at idle (when else do you have your head under the hood) when it is just normal injector noise.
Also, the grinding from the supercharger (if light) is usually air cavitation.

Kaeghl:
Good point, but note the occupation of JgaXKR!

It is not as simple as pulling off a valve cover which is quite a project. The tensioners are in the front of the engine. I will take a photo as we have 3 cars in the shop having this done now.
