- 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 CZcams 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,
@@ldnwholesale8552 welded parts iron casting's like 1970 426 hemi cracked/pited block or D-8 2020 heads for 400HP to 1500 HP and or flow modifying and or change's like adding sensors or cam phasers/roller lifter/60mm core or transmission patterns aka to say a hellcat bell housing thoughts 💭 ? and no i really for now don't have access to fresh castings or billet-steel for now, my personal charger/setup not for hire

also have access to scrap iron parts for practice ect and or a vary good at SS-welding not so grate at aluminium it's okay but not my thing
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.
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.
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

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.
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
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
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!
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
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.)
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!
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 👍
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 love this. It's truly an art form. Great job. That block is better than new.
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 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
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!
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 CZcams friends in Belgium who consulted on this. From Cummins to Jaguar, you two gentlemen do great work.
As someone in Boulder with a 1960 Mk2 3.8 and a 1969 e-type 4.2 I am ecstatic that there is a machine shop nearby that can handle these blocks and the details in a rebuild. Congrats on a success on this restoration.
I don't know a whole lot about engines as a parts replacer but I have a high amount of confidence in this repair.
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. 👍🏼
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’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!
Man, those machines. So large, so heavy, so strong and yet so precise. That is what amazes me. How something so...."Bulky" can be so gentle, precise with pinpoint accuracy. How metal can be cut like that. Man...that is craftsmanship!
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!
Just wanted to say, your workmanship is out standing ....
It's great to see a father and son team work so well together.
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.
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.
Just watched the videos of how you saved this block. Excellent work. I just rebuilt my 4.2 L supercharged Jaguar engine and trans. I owned the car since new so it was cared for . The engine had 235k miles on it and started blowing smoke bad. I removed the drivetrain and dissembled the motor . The machine shop inspected the internal parts and found almost no wear on bearings or crank. The piston rings were worn out and valve seals were bad. I'm having another experienced speed shop set the timing and I can soon reinstall the engine and transmission. The fact that you took the time to identify problems and researched solutions is amazing . The owner will be grateful you saved the block. Great videos
The order and cleanliness in your workshop gives an idea of the quality of the work AAA+++
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👍
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.
Most father son relationships could only dream to work as well with each other. You guys make an awesome team !
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 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
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! 😬
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!!!!!
"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!
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
It's a joy to watch this company perform high quality machining operation to the best of the customers advantage, not theirs. Keep on smiling.
This is just beautiful to watch. Really glad there’s a new generation of talented artisans preserving the automotive hobby!
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.
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 🤣
This is a good example of why a good machinist is worth every penny you pay him. Well done sirs!
As a mechanic watching your production is interesting and very satisfying. I think it's safe to say all us mechanics want to watch these processes in action. Thanks so much and I wish yall were closer to midlothian texas!
Block tease.....
I’d be proud to have you guys do ANY of my machine work that I need! 👍
I love the amount of care you put into your craft. I want the knowledge. Your craft is shrinking. My engine builder is 50 with one person trying to learn. All that knowledge needs to be saved.
"a freshly machined surface is satisfying in a way that can't be explained." I get it! I feel the same way. You do nice work. I'm envious. If I had to do it again I might have gone down that path in life.
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.
Man IM GEEKING OUT on this repair I love it. This is where not just math but experience and knowledge all come together. This is what sets y’all’s shop away from others!
It's a sign of true mastery that you still maintain the Zen "beginners mind" and stay open outside suggestions.
Let me echo my compliments to that Belgian shop for suggesting the tophat sleeve process.
this is the most satisfying block repair I've ever seen
Glad your continuing your Dad's legacy. We need more pros like you 👍
Brings back memories watching Pat Goodman machining Jaguar engines.
I've been a job shop/prototype machinist for 35 yrs. I think y'all are spot on with that repair. Good as "newsed". LOL
I think you guys just became the Jag go to people for this kind of work in the US!
Great work!
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. 😎😎😎😎
Where do I start?? LoL. First, Bravo to the folks in Belgium that not only watched the first video. But actually took the time to reach out. And to share some very vital information. And how they have had success in these types of repairs on these old engines. These videos that you have made to document this repair, should be considered educational in the restoration industry. And I have to say, You adding the voice over to the video explaining the process that is taking place is FANTASTIC. The time it takes you to edit these videos has to be kin to a part time job. The customer should be very happy with his decision to continue going down this rabbit hole. And to fix this severally damaged blocked the way you have. If this series of videos doesn't open doors for your shop into the restoration world. Then there's something wrong with the way the moon and the stars are aligned. There maybe be others out there doing this type of repair. But there "Dam few, And fare between" As you well know from your research on this damaged block.
Lot of dedication to your trade... Your dad taught you well, dont see that kind of commitment anymore. Well done.
I really do miss doing this for a living.. Engine machining was always so much fun, and honestly therapeutic too.
This must be my third play through of the Jag engineplaylist, I love watching you guys work and flex your knowledge and skill set as it shines through to your content! As an Design Engineer I miss my time on the shop floor on the machines, these videos always helps give me that machine and auto shop fix 👌🏼Nothing quite hits the same spot like the smell of burning cutting coolant.
Channels like this are why I love the automotive and machining industries so much. Passion and pride in workmanship is what makes the difference between a good shop and a great shop
Excellent, when I finished my apprenticeship in the 1960s I toyed with the idea of using a boring bar to do mobile rebores. Rebores were quite common in those days.
This is why your a true professional, you asked a question. Amazing work on the block!
There's something extremely satisfying about watching experts make challenging tasks look easy
It’s been 30 years since I’ve seen any machine work done. This video showcases your incredible skill and accuracy. Great job.
When I was young, I worked as a welder in a foundry, doing repairs on new castings. With the rods, wire and gas we have now, cast iron welding is easy if your oven goes high enough. But I wouldn't have wanted to do that block. It looks like a case of Jaguar over engineering to me. You picked the right method. I've rebuilt marine diesels for 50+ years. Every time I watch your videos, I'm impressed with your quality.
Those XKE's were dirt cheap in the 70's here in the USA since all had major engine problems caused by overheating. A performance parts company made a conversion kit that allowed one to install a Chevy SB and radiator to make those usable year-round.
Thank you soo much for coming through for the customer. Many people are simply too lazy to make the effort required.
I’m glad this ain’t tiktok or all the experts would tell you what you’re doing wrong! Keep up the good work and I love the content
Boring cylinders and fitting sleeves takes me back to my days as a moto mechanic.
I love that you tell us about simple changes you would do on process and how you plan to remember
Such patience in setting so many parameters to ensure perfection. I take my hat off to your persistence to ensure perfection. I have no doubt that that Jag engine will be a perfect runner.
This is awesome. I've seen lots of sleeving videos from Russia where sleeving blocks is an everyday thing for engine rebuilders. But this is by far the most comprehensive video on this topic from what I've seen. Amazing work!
As a journeyman diesel mechanic who’s done some machine work you are a skilled craftsman. Nice work!!
I am addicted to your videos. It takes me back. But so relaxing to watch someone else do it! Amazing work. Your shop assistant :) seems to be doing a good job. The experience is showing.
Big respect for taking this job. Most poeple back down when it's no that straight forward. Trying your best to help the costumer in house is huge. I love the dedication to details. It's hard to find such good people these days that are wiling to go the extra mile for a special cause.
I don't often like a video - has to be something fairly impressive for me to appreciate. I appreciate the attention to detail in this, every stage thought out and planned all to save a crusty Jag block. Good work and I hope the owner has paid well for it!
My Dad worked in a machine shop and would talk about what he did that day. Your videos have bought those stories to life. I do have to chuckle though with all the DRO's Mics, calipers and dial indicators that a good ol' Stanley tape measure still has a place in a machine shop.
This has been standard procedure for reconditioning Jaguar engines for a long time.
Later blocks, post 1968, would invariably crack or the sleeves would drop. Pre '68 blocks less so.
We were doing this in Australia in the 80's.
By successfully and skilfully fitting the top hat sleeves you have made this engine block an even better and more robust product than when it was new.
Leaving the sleeves protrude and leaving the assembly in a press overnight ensures they are positively seated.
What a special channel. The suspense of watching you machine and verify measurements keeps me on my toes. Can’t wait for your next video!
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!
You turned the cracks into extra cooling passages. Well done.
Awesome! At 2-hours after the premier: 15k views, 3.8k likes and 280+ comments. People are excited on how you resolve this complicated repair!
Insane! Thank you all!
Y'all's commitment to research to find the best way to save this important piece of automotive history is to be applauded. The technical methods to do it is outstanding.
Dennis Brothers fitted the same engine in UK made fire trucks during the late 1960’s early 1970’s instead of the more powerful and expensive Rolls Royce straight 8. In the mid 70’s I scrapped three 4.2 engines that had failed in the same location. It’s nice to see almost 50 years later a solution has been developed for a common problem on this engine. Pity the three I scrapped went to the breakers yard for scrap, reckon you could have given them a new lease of life.
Great video, keep up the great work and commentary, the pace and narration is brilliant.
I personally hate doing anything on by myself (doing only simple repairs or changings to save money). Nevertheless I'm really enjoying to watch your videos. No bullshit, no cringy humor only hard and dedicated, honest work. Keep it going guys!
ive got to say you made a seemingly boring task , exciting, instresing and informative i really enjoyed watching this video
I'm not a mechanic at all. Your explanations are very clear and concise. You and your dad are truly masters of your trade.
As someone who paid a bit of money for a rebuild, including machining and re-sleeving a cylinder that was out of round…only to just have to buy a used engine anyway a few months later (after the engine blew on the drive home…), I appreciate this job all the more. Nice to watch work like this.
(Also: recognized something about JIMSI, Sr. in the previous vid, and went back and found the short of him “running the parts cleaner” after 39 yrs (lol) and realized this was the same team. Glad dad was on hand to oversee…and to polish those welds for public consumption. Made sure to subscribe this time.)
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
I think it's great that you are saving "old iron". So many shops would just pass on trying to save an old European engine either because they are afraid of working with engine technology that they are not familiar with, or because they are not sure of their ability to do that kind of work. Personally, I love old Jaguar's, I will just never be able to afford one. I'm glad you are capable of saving many engines, that many shops would just pass on. Keep up the good work!.
Fascinating! In about I bought an XK120 FHC, with a well worn 3.4 engine. I was able to purchase a set of 3.8 JE pistons that had run in 12 Hours of Sebring. I took the disassembled block to a machinist in San Francisco, who bored it 3/16”, I think, for the larger, high compression pistons. The car was noticeably quicker. The enlarged engine served me well for the rest of the time I owned it. As a young Air Force B52 Maintainer, I poured evert cent I had into that car.
Now I understand why you do this job with such great technique, skill and love. You got it from your father.
