You can save thousands of dollars by doing general maintenance to avoid having to repair your blown head gasket. On my Jaguar Xjl portfolio supercharged I had to put in a new engine because I had a coolant leak that turn into a blown head gasket.

Great attitude to have . Man that car is now complete loss even if paid off . Thx for insight with me having a supercharged 5.0 I will keep this in mind fo sho !
Thanks for posting, great tip on renting from O'Reilly! What did you decide to do with the car? I just bought my first X351 2012 XJL Portfolio 5.0 with 48k miles. Jag dealer serviced a coolant leak before I took it home but I'm still smelling coolant… Having owned two X350 4.2L models I know how much V8 Jags love to leak coolant. Can't wait to dig into the 5.0 and get her buttoned up. Rear crossover will be the first place I look.
Coolant leaks, water pump and plastic coolant pipes are the talk of most Jaguar owners with V6 & V8 supercharged engines on a lot of Jaguar forums. When a new member joins in with a new Jaguar, other members on the forum chips in to warn of this problem that can be preventable. On a 2.0 L4 like mine on my Jaguar XF, I've NEVER read of any issues of blown coolant pipes.
Great video
How did the car drive when the head gasket was blown? And how did the oil look ?
great video
I had the exact issue to my 2011 Jaguar XJL.
Installed new engine as you did.
Yeah I have a 2010 XF Supercharged 5.0 and I plan to replace the front and rear cross over pipe this summer as this is a common problem with these cars. I think I’ll also replace the water pump and take the supercharger out to be serviced and looked over. Just want to have some preventative maintenance done.
why can’t you just resurface heads and block? and then put a new head gasket in?
Hey Bro I had a desire to buy same car. Would I be a great move to do so or I’m I asking for trouble?
Will you ever do a video on changing front or rear breaks? Don't think they are any different or harder to change from normal breaks, just would be a nice video for information.
These dealerships are the cause of the problems they rip off the customers YouTube is a very handy place for information and how to fix your cars
Hi Oxmanagain,
Quick question, why didn't you use the Bar's head seal as you did with your old Pontiac back in 2017?
Thanks
Have you had the transmission serviced yet on your XJ? I know Jaguar says its a lifetime trani & will not touch it. You need to find a reliable (yelp) local transmission shop that will do it. It has the ZF 6HP28 and ZF is a major manufacturer of transmissions. If your in SoCal – Oceanside Transmission handles these at a reasonable price & has 1 day trunaround usually with an appointment. Should be done ebvery 30,000 – 40,000 miles.
I tried this test and I can not pump it up to 29psi (200kpa) It's way to hard, it won't go past 12. Am I doing something wrong here?

Had just brought a 2014 Jaguar XF sc 3.0 and the next day off the lot it was overheating and error popped up low coolant. So I took it to a shop to be looked at the said I need a thermostat and water pump so I took it back to the dealership and they repairing as we speak. I plan on now renting the pressure tester and taking it up there when they say it’s ready to be picked up. So my question is when I do go up there if the pressure stay solid and don’t move my head gasket good? If it do move after a water pump and thermostat change then what that mean?
Not to call out the obvious; it's a supercharged engine the head gaskets won't last as long. That's what it costs to drive a race car. Naturally aspirated engines the parts last a whole lot longer.
i know you changed the water pump….so the crossover pipe was the leaky culprit instead???
Thank you for your insightful tip. I don't own an expensive car but from time to time, I always wonder if I had a leak in my car. The pressure test is simple and easy. Thanks for showing us step by step how to do it! Keep it up.
So sorry to hear this. I just bought and XJL Supercharged now I'm a bit nervous. Can I ask how many miles your car had when this happened? Also, it says in the description you put in a new engine, is that what you ended up doing?
Good to see you again but under better circumstances would have been better. I don't think many people would routinely pressure test their cooling system. I have been working on my cars for 50 years and don't have one. Didn't the Jag have a "low coolant" warning? My 2008 Range Rover had a warning. Looking at the coolant tank showed it was low. I just topped it up without further investigation but a few days later my brother noticed water dripping onto the ground under the engine. Investigation discovered a leaking cooling system hose which I replaced myself.
Did you explain what was happening to give you a reason to test.
Easy fix. Don't buy a jaguar. They are literal pieces of junk. Sure they run good until they don't and boy…are they expensive to fix!
