Tuesday Extra #3-How To Remove Jaguar V12 Cylinder Heads.
Вставка
- Опубліковано 15 вер 2024
- Perhaps the most difficult task when overhauling a Jaguar V-12 engine is the removal of the cylinder heads. In engines where the coolant hasn't been changed regularly, the fluid can turn corrosive and attack the face of the cylinder head as well as the holes where the studs pass through to secure the head to the block. Here's how to do it.
Interesting and terrifying in equal parts! Looking forward to seeing the condition of the head in the next episode.
Excellent videos, I have 3 V12 Jags a 6 litre X305, an XJS 1990 and a project XJ12 Coupe that I just got, all panel and painted but have to put it all back together, will be a long haul, but love getting out in the garage working on it.
Your videos are a great inspiration.
Thank for your excellent videos of the V12. especially the XJS! kind regards from Germany
Great stuff, I am going to pull the heads on mine, so very useful post
ABSOLUTELY AWESOME TRICK AND TECHNIQUE , PRICELESS KNOWLEDGE YOU JUST PAST ON TO ME NOW I'LL PAST IT TO MY SON. ITS PEOPLE LIKE YOURSELF ARE SO SO SO IMPORTANT TO OUR HOBBY. THANK YOU
Thank you so much for your comment and kind words.
glad to see somebody else using this method. i have used plasticene to form a well and pour in aluminium wheel cleaner. to do the same job as your penetrating oil. an RAF technician mentioned it years ago. and it works. recommended it to people on the forums but i think they think i'm nuts. always more than one way of skinning a cat. always interested in your videos. good info.
fantastic job, sir!
❤ thank you ❤ love the patient work😊
Nice job. I just pulled a very tough set from my V12. I made up a flat plate from 2 4" angle irons and managed pretty well. The pop bottle trick would have saved a lot of mess
I used to use a plate but found four bolts were all that were working at any given time anyway so these smaller units made sense to me. Plus, my plate went missing several years ago and I had the material to make these and so far so good.
Tips and tricks!
very impressive work thanks for a great show i love your little oilers briliant idea
Great information!
Great content. Really enjoying these videos.
Thanks.
Seeing this makes me want to pull my parts car motor apart for future possible need! Can't imagine anything cooler than having it stripped, rebuilt and at the ready! The thing is however Good fortune and God Willing my 89 xjs will just rack up the miles once I get done sealing it up.35k miles 2k post start up after 17 year hiatus. I wish I had your experience so that every incremental advance on my part wouldn't represent such internal high drama!
Everyone has to start somewhere. Just taking the parts car engine apart will go a long way toward demystifying it and encourage you to go to the next step.
I’ve done a video using the Jacking plate method.
an easier method is to remove the studs that are in the water-jacket. there are 20 of them. you don't need to remove any of the others for the heads to lift off by hand (as there will be no corrosion issues with the others). However - very importantly - you should not remove 5 specific water-jacket studs as they are more deeply-set in the block. They are likely to snap. That's 2 on the LH bank and 3 on the RH bank. All on the inside rows. So withdraw the 10 outer ones and 5 of the inners and the heads will lift off by hand
I thought there was a metal plate that you used...
More Please !!!!
8hrs for A head 13hrs for B head on my V12 still having nightmares
What is the issue with the B head?
ingenious
Thanks.
Nice.
Thank you.
What coolant do you recommend? Thx, useful video
I'm probably not the guy to recommend coolant because I'm alway working on my cars and they get fresh coolant waaaaay more often than recommended. I use concentrate off the shelf at Advance Auto Parts.
@@thecampchaoschronicles9567 green or the expensive stuff recommended?
@@omarks I just use the green concentrate.
@@thecampchaoschronicles9567 thanks! That's what is in my 6.0. about to flush it.
Given how many of these engines you work on, you might want to build a head puller plate like the one in this video. It works on all the studs.

There are plans in the XJS forum of Jag-lovers.
I've had a plate and used it for years. I like these better. These heads were the worst I've seen and would have given the plate at least as much trouble. Getting the pulling force out in front of the head made a HUGE difference. I'll be rigging up a similar setup at the rear of the head.
How does one critique without being critical, dunno? I keep watching your videos in hopes to learn or see something, but what I get instead is a whole lot of talking without hearing much, and however many minutes of video without actually seeing anything. How do you continually manage to do that 🤷🏾♀️？Who is supposed to be the target audience, or is this strictly your version of entertainment?
The target market is people who have an interest in the Jaguar V12 and to share my experiences with them. It's that simple. However, those who have extensive experience working hands on with the engine will probably not learn or see anything new. Thanks for the input.
What an idiotic comment! Don't watch, make your own videos and stop wasting everyone's time with your whining
Very creative headpuller, especially the angle iron part in the front and the bottle cap trick. I bought the massive headpuller from England (Google 'Jaguar V12 Head Remover'). Please let me know if you ever want to borrow it. It gets any head off in less than one hour.
