fyi - I was only referring to my 2003 Jaguar that I was about to sell to purchase an X351
- so if you would’ve read my earlier posts, you would’ve understood what I was referring to, but it is not important
please, let’s move
We don’t need to argue over a car. . Life is way too short -to argue
Thank you.
And yet, here you are arguing. I reread your earlier posts. It still makes no sense what you said, but instead of keep trying to shift blame to me for something nonsensical that you said, take your own advice and move on by not replying to post because life it too short. (We'll see if you can)
Good day everyone, I’ve recently been considering the purchase of a 2011–2014 Jaguar XJ Portfolio (X351). I understand that the available engines varied depending on the model year, with both the 5.0 L and 3.0 L options. I apologize if this has already been discussed, but I couldn’t find a clear answer. Could someone please share what I should look out for between these two engines, and any key points to keep in mind when buying one of these vehicles?
Last, shall I look for a 5.0 engine or a 3.0?
Thank you.
Good Afternoon,
I have a 2012 Jaguar XJL Portfolio 5.0 that I am considering selling. Some of the details are :
exterior color white with London tan interior
garaged since new
no dents,
No accidents, non smoker
Located in Scottsdale, AZ., so rarely ,if ever driven in the rain
Interior is like new, no one has sat in the back seat in probably 10 years
I am the second owner and have it since early 2013
I have every record since 2013
Current mileage 70,000, HOWEVER, at approximately 30,000 miles Jaguar replaced the engine and catalytic converters in warranty due to a catastrophic engine failure from overheating. I was driving over to San Diego on the I-8 at 85 mph when the engine light went on at
Jacumba, where there is no shoulder and I couldn't pull over. Car was towed to San Diego Jaguar and then over to Scottsdale where the engine and converters were replaced. So, there is approximately 40,000 miles on the engine.
The water pump and all cooling parts have been replaced in the past 10,000 miles.
Control arms , bushings, etc, replaced in the past 10,000 miles
This car is fast and quiet, its almost like a new car
In the past three years,maybe 2500 miles have been put on the car , since my wife no longer works , which is why we are considering selling the car.
If any of this interests you, please contact me
Thanks

Terry, maybe I can help with this question. I have owned both a 2012 5.0L NA XJ and a 2016 3.0L SC AWD XJL. Unfortunately, no 5.0L SC to throw into the mix. The one oddity you may find of interest is the 3.0L block is essentially a 5.0L SC block with the back 2 cylinders filled with aluminum (to make the V6). This was done to keep the different parts between a 3.0L and 5.0L engine to a minimum and to keep the 50/50 weight distribution for both engines.
As for mileage, I see it more as a draw. I was getting about the same with the 2 engines. So, do not let that be a deciding factor.
As for driveability. Again, I am going to pretty much call this a toss up. The 3.0L has a bit more umpf up in the RPMs, but the 5.0L will allow you to pass without having to shift gears. If I was to say anything, the biggest difference is the 5.0L motor turns about 2,000 RPMs at 70 MPH where the 3.0L is only turning 1500. This is mainly due to the 8 speed tranny vs the 6. Both cars will do a nice pull from 20 mph to 70 in pretty much 1 gear that will sit you back in your seat and get you around about anyone out there that you need to pass. I have currently about 105K miles on the 3.0L and had around 150K on the 5.0L.
As for things to look out for, both motors suffer from essentially the same problems except for 1 additional on the 3.0L. If these motors have a weakness, it is the cooling system. Whatever car you get, plan on dropping a $1000 and getting the cast metal cooling pipes and doing this right after buying the car. This will solve any worry you have about having a catastrophic failure. Sure, the 5.0L probably has a slightly higher failure rate of the timing chain guides, but this has been attributed to the Jaguar recommended 15K mile oil change intervals. Most people here will tell you to stick with somewhere between 5-7K mile oil change intervals. I was doing 7K mile changes and I never had to put on new chain guides after 120K miles (still didn't have any noise, so, I more than likely had a lot of life left). But, the 3.0L does suffer from a wearable supercharger snout that will make a bit of noise for you, especially on shutdown. Replacement is fairly easy and not that costly. The other issue that I seem to see a fair number of people talk about is fuel injector failures. But, both engines use the same injectors. The biggest issue comes from getting something into the fuel system and this will raise hell with the high pressure (can go as high as 20,000 psi as I recall, maybe only 5,000 psi, still up there) fuel system. You get any say water into the fuel system, this is going to hurt the fuel injectors in no time as the water does not lubricate them satisfactorily.
As a final note, you do not mention something that I find to be a big game changer for a lot of people. Auto START/STOP. The 3.0L engine has this built into the computer system and while it can be turned off, you have to push a button every time you get into the car to make this happen. The 2013-early2016 cars could defeat this by simply removing the aux battery. The later 2016 cars had no aux battery and it was coded into the computer. So, defeating it is much more challenging. Does the motor turning itself on and off on its own give you concern? The argument is that the worst thing you can do to a motor is start it. Now, instead of starting it once and driving 15 miles in town, you may drive that same 15 miles and have the motor start 10, 20, 30 times. All the more reason to have a high quality oil with short change intervals in use at a minimum.
If you have additional questions, let me know.
Newbie question...Where to buy the cast metal cooling pipes?
They're all over the internet and this forum- if you a search and you can find which brands people recommend and how to change them. I have a long post about them in my post history also.
Newbie question...Where to buy the cast metal cooling pipes?
. I look every week for the aluminum cooling pipes for my 2012 Jaguar xjl 5,0 n/an and can’t find them. All the ones I saw again today are for either the 3.0 or 5.0 supercharged versions and I’ve been looking for about 2 years. I was able to find a kit from Euroamp, but it did not include the pipes , I hope to find the pipes so I can change those out too as they are so very important.

Hi Thermo,
this is the kit that I bought a few months ago for a future change out. But , this doesn’t seem to have the what, I consider to be the two large curved pipes.
I’m not a diy guy and have limited knowledge of what some parts are called, I thought what I needed are called “coolant pipes “. which only seem to be available
for supercharged v6 and v8 engines. Maybe the N/A engines don’t use these “coolant pipes “ and the kit I bought is all that I need to change out ?
Btw, I’ve learned so much from you and some of the other members, without your input I wouldn’t know anything at all. Thank you for all the valuable inf, let me know about those two coolant pipes.

Do you mind sharing where you found the 5.0 SC pipes? Thanks.
Yes so far there are no metal cooling pipe for the front 2 pipes for the NA version. They have been promised but I think the low production numbers for the NA versions are the problem.
Very good advice from the above posters.
That V-6 engine is a real strange one too!
Yes that is a glass topped coffee table! They make them with many different blocks too.
