This is the numbers matching engine block out of a 1968 Jaguar E-Type Series 1.5. Unfortunately, it seems that the 4.2L Jag engines have an inherent design flaw...
Will the top-hat sleeves we installed be the answer?

it would be awsome if you could eventually show us the running engine.
I would bring any motor to you for build prep. sleves, decking, head work and valvetrain reworked .top of the line work you guys do is outstanding
I'm doing a olds 455 rebuild. and the block will need just about everything done. I wish I could send it to you guys. but I'm too far away for it to make sense.
How many psi/pressure do you use for the Hydraulic press
Why not weld up the crack and then bore
Credit to the Belgian shop that was willing to share their process. People like you make the difference in an otherwise dog eat dog world. Thank you!
I mean in the grand scheme of things, no real love lost on their part, since it's not likely they'd be doing this job. So pass the process onto another tradesman.
And this has allowed a rare matching numbers block to be saved!😊
In the more Niche Fields it's all about building relationship with the other shops and especially the old Gearheads from production days. It's amazing when you find that one person that happened to be on the initial production team or has every imaginable measurement and schematic. What comes around, almost always goes around
For sure. So many “secrets” in the trade that just makes things hard for others. Really great to see shops helping each other, and of course JAMSI for sharing with all of us.
Sharing this kind of information allows for more innovation later sooner
Never seen anyone work so hard to save a questionable situation. I hope the owner sees the video and appreciates the effort it took to save it. You guys are the bomb...
That's the world we live in today
oh I can promise you he'll be paying for it the owner obviously is trying to say this car and keep it original numbers at any cost needed to do so
pretty sure he will appreciate it by having to open up his wallet :)
Hopefully as they are making this successfully KZhead series they will heavily discount the price he has to pay. The reason of the appeal of this video is the rarity and value of saving this particular engine...
This is a really common problem with the 4.2 XK block,. If you've never come across these blocks before it's a bit daunting, but this repair is a very successful fix. I restore E types; this is what we always do.
My grandpa would be proud to see that block made better than new and being put back to work, serious Jag guy he use to set them up for the 24 hours of Lemans. I loved the machining and really enjoyed the video. My gpa watch the video with me and it's the first smile he's had in a long time. He's recovering from brain cancer and can't talk or walk anymore but understood the whole video.
For racing that block is junk, for highway cruising they have done a very good patch.
Hug your grandpa, tight,,,, kiss him too, if he will let you. 🙏 🖖 🙏 😔 🙏 🙏 🙏
@@ldnwholesale8552 i think he was saying that his grandpa would set up other jag engine for racing not this specific inline 6,

As a 40yo car guy I can say that nothing I’ve done while working on cars has ever gone this well, I’ve changed tyres with more drama than this. Real credit to you guys, true workmanship.
Manually changing tires is the most physically demanding job I have ever done on a car. And I've done my fair share of big jobs.
I have no mechanical or engineering qualifications and have never worked on an engine but I love to watch engineering/mechanics
@UC2ClAVKKnLPZL8X5LhfdzLA ur right I don’t think he addressed the cracks but doesn’t the sleeves covering them address any potential leaks ? That said though the cracks still managed to form whilst under the original sleeves so they probably gonna keep growing
@@msquared6695 The cracks are at the top of the deck and are stopped by the machined cooling groove below it. If those hadn't been there, the cracks would likely get bigger, but I think that ends it.
Watching these guys make such a challenging issue look easy to overcome is so satisfying. The mark of a true craftsman.
I'm very happy to see this old Jag block being brought back to life. I really hope the owner gives us a video of it running when you're finally done!
I will have to ask 😬
@@JAMSIONLINE Please do. Looks like y'all have rebuilt this block better than new. I & many other viewers will appreciate seeing this fine old machine making that sweet Jag exhaust music.
It's great to see how far the cleaning guy has come these last few months. Took him a while to get the hang of it, but he looks to be progressing nicely. 👍
As a machinist myself, absolutely outstanding work. It's obvious that you take pride in your work and the end results clearly show it.
I’m a machinist by trade but don’t work on engines, Its quite a sight for me watching you jump back and forth between a bore gage and a tape measure. I really appreciate how much thought and thoroughness you put into the process.
lol important to know the tolerances required in each situation. Setting the depth of the stop on the machine in this instance is a + 1.000 -.000 type of situation so tape measure fits the bill
As a machinist in a job shop, I enjoy seeing the tools, techniques, and machines y'all use. I assumed the machines would be highly specialized, but it's always fun seeing machines you've never seen before do their thing.
Walking through a machine shop is always fun and fascinating
Keeping that matching numbers block is certainly worth the cost and effort. More importantly, is the fact that you've effectively eliminated a design flaw and insured a workable head gasket seal that will allow the car to be used as it was intended. Fantastic work guys.
Indeed that looks so good it may still be running in another 100 years time . Modern fully synthetic oils and filtration plus modern petrol have absolutely transformed engine wear . When I started driving we had only straight 30 or 40 grade mineral oil which broke down so quickly and afforded no protection . Forget all manufacturers sales biased oil change intervals - use appropriate grade of fully synthetic and change oil no greater than 6000 mile intervals - as long as you do not overheat the engine it will carry on indefinitely .Modern oil is brilliant .
@@richardhintonracing indeed
What is done if the block absolutely cannot be used, cannot be repaired by anyone and numbers matching is desired? It's my understanding you can't simply swap the engine numbers as it's part of the casting or is pressed in such a way its near impossible to remove

My dad, I’m 75, worked at Packard during WW2. They were making the aircraft engines and PT boat engines. They used differential temperature for several subassemblies. When you live in Detroit, these are the things your dad tells you that you never forget. Thanks dad. Rip
Superb work. I hope your customer understands how fortunate he is to have entrusted this critical work to you and your dad. Your skill, experience, and attention to detail are exceptional.
They did a nice job, but they're far from alone. Any machinist with years of expeience working with engine parts are going to be competant enough to handle this. If they're not, they wouldn't have reached their years of experience. They run into stuff like this all the time.
@@kellyappel3015 Certainly not alone but still exceptional based upon my experience. As the saying goes, your experience may differ.
@@theodoreshasta7846 Agreed. THere is a reason you need to 'ask around' before entrusting an engine to a shop. they aren't all created equal.
Oh so true, you can all the best equipment but if you don't care about what you are doing it is wasted. These guys seem to be in the care category.
@@theodoreshasta7846 It does. I relied on a couple of guys in my area for years. One moved on, the other retired. The guy that replaced them has been just as good. All three of them would've come up with a solution for this block (probably same solution as Jim's.)
AWESOME JOB GUYS!!! Preserving history like this is such a satisfying accomplishment. LOCTITE 620 is perfect (as you well know) for this kind of job. I've seen it used on inserts to rebore rifle barrels. So, with a shear strength of 3800 psi, you know it will handle a shock load. Also, it's bond breaks at around 450⁰F, so it'll definitely take prolonged heat exposure in an engine cylinder. I'm so proud for y'all for the success of this project.
Thank you!!!
I'm a second year apprentice machinist; I originally wanted to be a car mechanic bur fell in love with machining! Your channel has given me a great direction for me to aim for in my career!
You and your old man do some awesome work!! My dad's a auto machinist by trade and has told me all sorts of stories about the engine work he use to do back in the 80s to mid 90s here in New zealand before I came along, it's really neat to see that shops still do this level of work and can save an engine. Most people just throw shit away theses days. Learning/working with your dad must be pretty cool to! I worked with mine for about 5 years and it was the best. Keep up the good work dude 👍
You make machine work appear approachable! I hope this means more young people will follow in your footsteps so we don’t lose the plethora of knowledge learnt by the generations before us! This is amazing as per usual!
I hope so too! I often wonder if young people are taking interest from my videos. Don’t want to be cocky, but I hope they are!
@@JAMSIONLINE I for one take great interest in your videos. I'm not young, though.
I (ex-auto mechanic) have been trying to get one of my 3 sons to learn the machine shop, welding, etc., but between computers and the Navy and the Air Force it probably won't happen. On the flip side they can work a 3D printer like nobody's business, so there's that. Also, the kid down the block is apprenticing in a machine shop and he just graduated college to work full time, so there is hope!
This kind of work is how you build an impeccable reputation. I hope you like challenging projects because you're going to have a lot of people thinking about your business when they have a challenging project. Great work and I can't wait to see the rest.
I like a challenge. Just have to pay the bills as well lol
@@JAMSIONLINE Fair & reasonable pay for these abilities - which not everybody can offer - is the reward for mastery of your skills. If y'all were surgeons, I hafta think you'd be heart transplant specialists or wizards of re-attaching severed limbs with full function. Yall's abilities to understand and solve problems is high order. May not be alone but y'all gotta be at the top of the pyramid. 👍🏼
The level of dedication, careful deliberation and commitment to excellence is simply incredible! Another excellent example of why I love the JAMSI channel so much! Your customers are blessed and I'm envious!
It's great to see a father and son team work so well together.
I love this. It's truly an art form. Great job. That block is better than new.
Absolutely fantastic. In high school I worked in an English car repair shop where there were E Jags all the time, so I love this project. Shout out to your KZhead friends in Belgium who consulted on this. From Cummins to Jaguar, you two gentlemen do great work.
Being a tech who relies on quality machine work, it's really satisfying to see the detail yall put into your work. And taking tips and tricks from someone else to give your customer a better product says a lot about trust and work ethic.
I’m new here and I like cars but I’m not a “do it yourself” guy. I’m a software engineer with mainframes so i understand working with old tech and finding creative solutions. Just wanted to say that your channel has become excellent background noise for me. It was during this one that I realized how much effort goes into these! The production quality is great and when you said “The footage comes second” I really appreciated that. You can tell you have a passion for your craft. Please keep making these! And give your cleaning guy a raise!
It’s hard to believe this is your first time doing one of these Jag blocks given how adept you are at it. It’s almost like you’ve been machining engines for years! But in seriousness I think your content is fantastic and I’m super happy to see you are here in Colorado!
This is an awesome series and I'm just a gearhead. Love that you're practicing your craft at the level of real art due to numbers matching, available options for repair, etc. And bringing an old Jag back to life is never a bad thing
I don't know a whole lot about engines as a parts replacer but I have a high amount of confidence in this repair.
Just wanted to say, your workmanship is out standing ....
I can't Imagine how much time these videos take to make, The machining alone is a long process, but to setup camera angles at the same time, I salute your hard work.
Always love that you explain the thought process of your choices. Can’t wait to see the whole engine come together
The order and cleanliness in your workshop gives an idea of the quality of the work AAA+++
I love watching these videos that y’all put out. I’ve been an electrician for 19 yrs but wish I would have got into machining when I was young. Such talent for sure
I've never done this kind of work, I'm finding it very fascinating. I would never thought that block was able to be saved. Just goes to show that given enough time and money anything can be fixed. Great work guys.
Don't work with cars or machining but love to watch them both. That makes this channel the best of two worlds. Really interesting with older engines like this Jaguar.
"satisfying in a way that can't be explained". That sums up the feeling I get from watching you work! I'm a Motorhead past his prime, and the tech today has left me in the rearview mirror, but I have rebuilt a few motors in my day, and I can only wish I'd had the knowledge then that I've gained just in the time I've watched your content. Keep em coming and this old stripped gear will appreciate every one!
I am amazed at your attention to detail! Obviously necessary in this line of work, but I doubt that many others strive for perfection like you do. The next time I need machine work done, I think it would be worth it to take the drive to have you guys do the job. I know I wouldn't have to second guess anything and it would truly be as perfect as it can be.
this is awesome! i particularly liked that you decided not to try welding or brazing, not because its impossible, but because you're honest enough to say that you would not be able to do it at the quality standard you've set for yourself and your customers. admitting that you can't do everything and choosing the method you can do best is a great quality to have👍
Can't wait to see this up and running. I love this kind of work.
Awesome work. The attention to detail is amazing. The extra work you’ve put into this engine to save it is great.
Amazing work as always guys I wish there were more machine shops around like you unfortunately it's kind of a dying art.
Not gonna die while I’m around! 😬
Are you proud of what you’ve done with this channel? Your videos are precise, concise and informative. You may think that’s obvious but watching other channels makes those qualities unique. Great job making videos of your great job on this engine block.
Awesome work. Great to see you come up with a decent and practical solution for your situation.
Great episode. It was really encouraging that another shop was so willing to share their repair techniques with you. Looking forward to the next episode.
This came up on my notifications, I subbed cos I want to find out the fate of the jag’s block. Only to be met with this being a premiere for the next day. *Fum’in*
It premieres in 20 mins tho….
@@JAMSIONLINE Math's is hard
Thank you for taking the time to film all this!
I have been a machinest for 30 years . Working in aircraft to tool and die work. I realy enjoy watching your dad work and getting to see old-school work to the modern application. Great work
I hate premier style video launches! Just lemme watch it as soon as I get notified!
Same !
Agreed! 😡
I know that this video will contain tap magic
I don't see the point of them.
@@timothyball3144 purely selfish I guess. I like seeing how many people watch at once and interacting with people in the live chat. It would go live at 5PM Mountain either way. Y’all are sure picky about your free entertainment 🤣
Block tease.....
I got my start as a mechanic in a British sportscar shop and this is exactly how we always done the 4.2L jag engine kudos buddy it's good to see that there is still people out there working on these old jag engines!!!!!
Just beautiful work - a joy to behold!
Long time cylinder head machine shop manager, very rarely do I see an appropriate level of attention to detail. Thank you for keeping it alive for the next generation.
I really appreciate the work and care you bring to your projects.
Wow... What a save! Brilliant work!
Absolutely LOVE this content. Love that detail, love that it's edited well so it's engaging the whole time, love the technical detail you provide. This is absolute gold, and I SO look forward to the next video on this Jaguar engine, and I'll definitely be taking a look at your other videos. Cheers!
Im glad you are doing some thing I have been doing for years.
Awesome to see it all coming together. I know that stress all too well. Having those rare pieces and you just want everything to be right. Great job guys!
Absolutely incredible. You and your dad are the real deal! Thank you
Awesome video. So stoked when you put out an update on this motor. You guys do such excellent work. Thank you for sharing the process with all of us
Fantastic level of detail for every step of the process. Your care and diligence is inspiring. Keep it up!
I did understand this process, but watching you guys fit these sleeves was amazing. I've owned a few jags and to see you save this engine was very rewarding. 😎😎😎😎
I love that you tell us about simple changes you would do on process and how you plan to remember
This is just beautiful to watch. Really glad there’s a new generation of talented artisans preserving the automotive hobby!
I love to watch your machining, such an overlooked art.
Well done guys! Love to see high quality machine work
I've been waiting for the finish of this. You guys did a great job. Always enjoy your content.
Wow! It's brilliant to watch the precision of the work you do. And great think that a Jag block will live on.
Very well done! I'm excited to see the whole engine after you finished it!
Awesome video. Enjoy seeing these type of videos showing different ways to save older parts!
Really enjoy the detailed explanation for everything.
Love this series. Its great watching highly analytical people walk through their process.
Nice work, real craftsmanship.
I really do miss doing this for a living.. Engine machining was always so much fun, and honestly therapeutic too.
Really appreciate all the time you put in to making these videos for us. 👍
Fantastic work. Looking forward to the next one on this engine!
Great content, numbers matching is rare and glad you were able to keep it original
Hugely impressed. Great problem solving.
congratulations on your thoroughness and attention to detail in all aspects of your work. A tribute to you both. The quality of the videos is just the icing on the cake. Thank you, thank you.
Unbelievably solid work gentlemen! A great education on putting in sleeves on an old iron block, I enjoyed seeing you & your pop working together.
Absolute perfection.. Just beautiful work
Just found the channel a couple days ago...so satisfying to watch. Great job!
Excellent stuff. Great that other shops are sharing their knowledge and that you guys are breathing new life into old, irreplaceable engines
Love watching your processes and explanations are so simple to understand on the why, how , and what you are doing . Keep posting.
Great work. Awesome to watch you guys put so much care and attention into everything you touch. Keep up the great videos.
This is just so satisfying to watch. Awesome stuff and so good to understand your thought process and how you came to the decisions that you did. Brilliant.
Great work! I really like seeing how you problem solved this issue. I feel like this happens more often in shops that do quality work.
The way you describe all the details is totally awesome. You and your dad really operate in a very excellent manner. Thank you. Jim
These guys are top of the line pros! I am impressed.
Love to see this, strong machining work and a great repair not replace mindset 👍🏼
Great work guys! Love seeing how you guys were able to overcome a big obstacle.
I’ve found this channel very recently and can’t stop watching your videos. My grandfather was a machinist and sadly died when I was two, but it’s very interesting watching these videos and getting to see the kind of work he spent his life doing. I still have the sign from his shop, and somehow inherited his automotive skills despite them skipping a generation
Excellent workmanship
Seeing all these different techniques, tools and on the fly adjustments in the process really tells me you people know what you’re doing. Your videos and comments keep improving after every video, I absolutely enjoy each and every one I watch. A must-see for everyone who has heart and soul for automotive techniques.
Top tier work. Wish everyone took as much pride in their work as you do
Absolutely incredible works gents! Wow! And your narration is impressive, so many steps to concisely describe. Excited to see the next vid
Nice. So precise. Well done.
Nice work. I'm looking forward to the next installment.
I’d be proud to have you guys do ANY of my machine work that I need! 👍
Outstanding effort and workmanship!,
Watching your videos gives me a real appreciation for what engine shops can do. Being a toolmaker by trade I know how satisfying it can be when you figure out how to do that ‘impossible’ job. Keep up the great work!
