Outstanding block save ! You and your Dad are definitely Craftsmen of the highest order.
I am a 72 year old gearhead who worked as a mechanic for 53 years. My nickname is Moparman so I guess you know my forte! I did a lot of my machine work but it was benchwork. I wish you guys were around when I was racing. One of my endeavors was a Dodge 225 slant 6 which everyone laughed at. I got lucky and found a Swedish machinist in Miami Florida who painstakingly blueprinted my short block. My end result was a 1961 Plymouth Valiant that ran 12.12 seconds quarter mile at 116 miles per hour! You guys are amazing!
I have a 76 dodge dart swinger with the 225 that I was thinking about building for the plain and simple fact that no one ever runs those and when I blow the doors off of a v8 car, I want the guys jaw to drop when I tell him it’s a six cylinder🤣
This whole process was fascinating, you and your dad have a right to be proud. At some time in the future would love to see the E-type when the restoration is complete.
I agree with you, but they’re only doing the engine
I would love to see the motor running.
@@bbrewe71 Yes so would I
@@dirtfarmer7472 they owe it to us for goodness sake!! 😆😆😆
Fascinating?! This is boring.

Craftsmanship, pure and simple. Doesn't come any better. A pleasure to watch.
Guys, for somebody who once rebuilt a 4.2 XK engine from a bare block, this is an awesome video ! Congratulations ! Way back in the late 80s, I suffered the dreaded block cracking between the bores. I was fortunate enough to find a chap whose job was rebuilding these engines, and he told me the cure was to insert lipped liners, (top-hat liners). However, he sold me an uncracked standard size bore block that just needed slight honing. Up until your video came out I had never seen the full process. BTW the low areas between the bores after your first pass on the block deck shows the effect of the cracking. The crack means the strength of the bridge of metal above the first coolant passage is lost, so sinkage occurs. This, of course, means head gasket failure occurs and will keep occuring until lipped liners are installed. Some shops will just face off the block and think all is OK !
So can you be rough on the block now or daily driver? Or is this more now a very easy driver, stored for collection purpose?
@@bridgefan87I’m not the OP but, it should be better than new. That was kinda the whole gist of the video if you didn’t watch it all.
The original iron block can hold the top hat liners very well and since the cast block can’t collapse beneath the head gasket like it did originally, that common failure point won’t exist anymore.
The rest of the engine is pretty solid as long as you keep oil and coolant in it, but an updated rotating assembly wouldn’t hurt, lightened and balanced, (roughly a couple thousand dollars at a machine shop) would make a really long lasting engine, really only limited by oil pump and cam wear, but that’s kinda overkill, these guys are standard setting professionals and they use standard pistons and rods in this build.
My Dad served his apprenticeship as an aircraft fitter in the RAF during the second war in the days of poured babbit bearings and hand scraping surface plates - I had the great good fortune to spend my teenage years working in the shop with him - it really warms my heart to see you working with your Dad like I worked with mine
I have s friend that has his own machine shop, he has done all the Machine work on 3 complete reman engines for me, plus I have watched him do numerous jobs for others. I always enjoy watching machine work. He bored, honed, decked the blocks, and resurface the heads along with complete valve jobs, rebuild rods, and balance. I find it very interesting. Watching you and your crew is enjoyable. Thank you sir. Hope you and yours have a HAPPY THANKSGIVING. 😊
Thank you! Yoy as well!
Wow! Amazing work!
Absolutely stellar work.
With men like you and your father it seems anything is possible.
Thank you!
Well said. It restores faith that we can still build things in the USA.
The whole process to keep this Jaguar engine in it's numbers matching Chassis was a delight, and I am so glad you decided on this methodology. I am absolutely certain that when you say "better than new" you really mean it, because your work speaks for itself. That poor engine was shot before you breathed life back into it!
its*
Always a joy to see a craftsman taking a genuine pride in their work.
Thank you!
I’m 70, my Dad owned a scrap yard and 2 part stores, 1 a machine shop. I watch you father and it brings back memories. My brothers and sister worked for him growing up. I didn’t follow him into those businesses. It can be a very challenging thing to do. You do a good job.
Working with family is tough for everyone lol. But we are getting by :P
The cleaning guy has become such a star ⭐️ recently… I’d forgotten what he was like early doors.
I am a retired Automotive Machinist/Instructor. I love watching your videos. You both demonstrate mastery of your skill/profession.
Would love to hear how the rebuilt engine performs. If the owner puts it on a dynamometer and verifies it's out put to spec etc.
Really enjoyed this series. Thanks!
Absolutely! Would love to see finished engine in the car.
The owner of this Jag is lucky to have you guys to do the machining. Very interesting, and informative.
I'm an old man with no experience with anything like this. Makes me all the more amazed, impressed and blown away by your skills and craftsmanship. Total respect for all of you
The professionalism of you guys is like poetry in motion. Thank you Jim and Nick for showing us through your shop. Keep up the good work.
I have watched this block from the beginning and was sure it was scrap. What a transformation. Awesome work (even the cleaning guy)!
Let me just say, this is the only machine/mechanic channel I watch. I love your videos and the educational quality you provide. Keep on keeping on!
I do love the little man!
If you enjoy these videos you might like cutting edge engineering Australia. Similar work but he does hydraulic cylinder and barrel repairs and replacements for big machinery very fun to watch and very educational. But these two are for sure beasts at what they do and take a lot of time and pride to make sure it’s done right
as a cleaning guy with a 13 year old that just completed his first soldering project, I inspected his work a couple times and had the same reaction as your cleaning guy...pride in my sons work.
Hope we get to see that motor running when finished. Absolutely awesome workmanship, unfortunately getting harder to find someone who actually cares about their work like you guys!
Amazing work. My father passed before I was old enough for him to teach me automotive repair and watching you and your dad is like gaining the teachings I never got. I'm a backyard mechanic but I enjoy rebuilding motors when I can.
You guys should smile nice and wide for the work you both put in to save and return this block to service for the customer. Numbers matching means a great deal nowadays. Thanks for your time guys!
Thanks for being an integral part of keeping the machines we love so much on the road.
It’s been probably 5 years since I have ran any machines. I am retired/ disabled. I like watching your channel brings back good times.
I spent nearly all my working life behind a desk but find this type of work extremally interesting and entertaining. No regrets, I just admire all types of excellence.
Never too late to start 👌🏽
Always a pleasure to watch a true craftsman ply his trade. You and your father do beautiful work.
Hi my name is Jim , I really like how you guys work together. All of the machine work I have watched on your channel is spot on and clean . I have been a machine technician most all my life , and I would not be one little bit concerned about having you do all my machine work for me ! Keep up the great work you guys do ! 👍 by the way I am 60 years young ! 😁
It is art. Thank you for giving a classic car a heart better than new. Re-engineering out faults is an art and a true calling.
It’s been over 30 years since I’ve done any machine work. Growing up next to the farm my mentor had, we would grind valves and seats which put me ahead when I went to vocational school for auto mechanics. I spent 30 years wrenching and seeing the machine processes does not get old with me. I appreciate a good machine shop as they can make or break you as a tech.
We used to have an engine machine shop in my home town, the owner retired and nobody wanted to continue. So now I don’t know what people do when they need this kind of work done
Great respect for helping an old jag back on the road ...they need all the love they can get !
I have to say that I am in absolute awe of the work you guys are doing and in my opinion the logic of the choices you have made, in order to try to save this block, is spot on. The attention to detail that you apply at every stage is of the highest order and it is so fantastic that there are still shops like yours working to such high standards.
I know it's probably been said a thousand times before, but just watching all the steps that go into getting the block back to perfect is astounding and so watchable. Glad I found your channel.
I’ve watched a many hours of UA-cam in my day and I think you’ve created the greatest video series on the platform with this block. At least in the machining category. Fantastic work!
I personally do not know you manage to read those gauges so accurately must be something you learned early on watching the cleaning guy! Lol
I throughly enjoy your videos, you sprinkle in just a small touch of humor here and there while keeping the overall video about the work. Your explanations of the process make complete sense without the need to look up definitions. Keep up the great work!
Coming from a machinist back ground
in the bearing industry. I truly appreciate your attention to detail. Good job.
I love to see precision work done by an expert. So satisfying.
The story of this Jaguar block has been fascinating to watch. Thank you for the high quality videos and for explaining all of the steps you take. I'm not a machinist but I really enjoy learning about your work.
Incredible work. That is the cleanest machine shop I've ever seen. Every button every knob might be old but they don't show years of oily hands. Lot of pride in that shop.
I hope that the enjoyment I get from watching you work is reflected on extra work that YT generates for your shop. The benefit of a shop this size is that there is a great deal of care and ownership from the people doing the work. This is not always the case in larger shops. Attention to detail is a thing of beauty here. Love these videos.
Really nice work! I enjoy your videos and the attention to detail. The block turned out fantastic. Keep us informed on the status of the build if the customer gives you updates.
Thank you!
Thanks for taking the time to share this series of videos. Excellent work!
Enjoy your time with the cleaning guy. He will be missed when he is gone. My dad has been gone since 97 I think about him all the time. It is awesome that you guys work together
You do beautiful work. Nothing wrong with taking pride in your craftsmanship.
You guys absolutely knocked it out of the park! Just know that you’re work is admired and appreciated. Thank you and keep up the great work, I love seeing the channel grow!
I learned as a child to love the smell of a machine shop. Thanks
My dad has a 1975 jaguar xjc6 with this same engine as a project and when we took the engine apart years ago we were suprised to see zero cracks in the block. And only now that i've been watcing your vids on this block i realize how much work that lucky find has saved us.
Excellent video! Love seeing your family machine shop do these rebuilds! The longer the video the better!
I see JAMSI ... I must see 👀
Less than an hour :)
It is amazing to see this world of "repair it instead of buying new" on a whole new level and to see all the things which can be done to rescue a classic engine. I love the concept and especially the fact that you guys make a living out of it.
And the cleaning guy must be so proud of the new guy for working in the same shop together. absolutely perfect!
This project is what brought me from just watching the shorts to watching the full videos. You guys kick ass!
That cleaning guy is worth his weight in gold! Make sure you keep him around as long as possible! 🙂👍🏻🇳🇱
I lost my "cleaning guy" about 3 years ago. He was a wealth of knowledge and experience in Chevrolet performance. I learned all I could from him. Take good care of your "cleaning guy". Very important in your life!!!!
Love your content keep it up😊
Thank you! Will do :)

Hi there. I think you allready notis. That spamers have clutterd up the comments.
I have manualy help you report over hundred of them. But to prevent future spaming. Ther filter programs to automatic report and clean them up. But it is onley the channel oner that can run the program.
Love youre work. And i hate to see it spamed!
Janne from Sweden 😎👍
Yes I appreciate it! Unfortunately the setting is already enabled and it is not doing a very good job of filtering the spam!
I remember back in high school, we could take a automotive class. The first year you brought in your own Briggs and Stratten engine. You broke it down took measurements and learned honing, valve lapping, everything. The teacher was old school and if you gave a crap, he give you knowledge second to none.
The second year, was advanced automotive. Here you tore down V8 engines. Some kids acted like they new everything and he told them to leave. The rest of us kept our mouth shut and learned volumes. If he saw you were really serious, he was a great teacher and shared all his knowledge
Thanks for the information and enjoyment! I'm 82 and although I'll never be able to use any of this knowledge, it's fun to watch and learn!
Fascinating video. I just completed rebuild of my 1970 E Type. I was fortunate enough to have a fellow, like you, who learned how to properly machine a block from his father.
Amazing video. I had a new 1967 4.2 E Type back in the day, down in New Zealand. I loved that you lavished so much care on that block. A true work of art. You must be proud....
Having bored and honed hundreds of motorcycle cylinders, in my day.
I appreciate the attention to detail throughout the process.
Especially the final cleaning of the cylinder bores.
Just like cleaning a gun bore; patch until the patch comes out the way it went in.
Great job!
Wow, the 3 video process of saving this irreplaceable block was just about the most fascinating thing I have ever seen. As an old Drag Racer I’ve spent quite a bit of time in a machine shop. I am so glad I discovered your Channel. The pride you have in your work is very impressive.. thank you for sharing!!
I have to admit, I know nothing about machining engine components. But even without that knowledge, I can still appreciate and enjoy the precision and artistry of your work. Thank you for introducing me to your world. Kudos!
Times have sure changed. As a very young man, I had a 3.4 L XK120, well worn. I had an opportunity to buy a set of JE 3.8 L pistons that had been run in a D Type at Sebring circa 1961. The machinist decided that Plymouth piston rings would fit the pistons perfectly and bored the block. No sleeves were required or used. The engine had much improved power, and was running strongly when I decided I’d had enough and sold the car. The difference between the machine work done than and what you’re doing to this Jag block sure point out the high technology available today. Well done👍👍.
One thing that I admire the most is the continuously checking of the numbers, making sure the calculations are correct and Dad the QC master. It takes tremendous skill to work these machines and I see one of the most important skills: patience. There is no such thing as a rush job. I worked at various machine shops, some reman, some new and the amount of man labour going in with the reman is far superior to the robot driven new blocks. Like others, would love to see this engine reinstated in its car, matching numbers will certainly help at concours to get high scores.
You all clearly know what you're doing. That's refreshing. Could watch you do that all day.
Agree, the finished product is a thing of beauty.
:) I thought so!
@@JAMSIONLINE
I am a retired machinist and I know what good work looks like. Your dad and you know how to to it.
Sir fixing a cracked engine is definitely a work of art!
Oh come on now. Are you kidding me. Was smiling a big smile at the end here. So wonderful for me to see these processes. And for you to restore that block to better than new, so that ol Jag stays on the road. That is a thing of beauty.
Love the cleaning process - I was once told when 10 years old rebuilding my Sturmey Archer 3 speed bike gear box - cleanliness is next to godliness- glad you had the same teachers- so many times this is overlooked.
It's tough as a former mechanic and life long gear head to find content that I actually enjoy. Thank you. You and your "cleaning guy" obviously know what you're talking about 😉
That's nice work! I wouldn't have thought that block could be saved. There's something deeply satisfying about the look of newly bored cylinders. I can almost hear it running!
Came here after watching a few shorts and noticing the quality of work and care you put into your work
I love the patina on the Sunnen bore indicator sight glass when the "inspector" stopped by
well done. so awesome to see a small family shop do such old-school work together and teach the world at the same time. thank you
The care and workmanship I would say equals anything that is made in the aero industry, mesmerising.
I have no clue about engine machining and love to watch all you videos. one thing I can definitely tell you did right in this video is that you researched and consulted other professionals about it rather then going ahead with what you thought was right! 👏
Not only a beautiful job ! But you and Dad always go above and beyond for every customer !
Dude! I'm not into cars at all beyond a healthy appreciation of going fast.
Watching your videos has made me really start to love the art and precision craft associated with beautiful auto design and repair. Thanks!
Excellent work gents. Reminds me of a 289 block that came in. Had been sitting in a field for 25 years. Asked the owner if I needed to take it to scrap bin. Said no, we’ll be building that. I’ll just say after three sleeves and all machine work it looked like the day it was made. You and your dad do great work. Keep at it.
Jaguar guy here. Wasn't always. My dad had a love for the XKE. So he bought one in the late 90's. I inherited it. That engine block is the same age as myself. If I need some work like this in the future. I'll look you up.
Very interesting work you did with this engine block. I'm an old school type of engine mechanic and I enjoy your videos, they remind me of the craftsmanship that some shops really strive accomplish.
I gotta say that cleaning guy comes in handy and never hurts to have a double check triple check and all that washing wow for sure clean clean clean great job customers gonna be totally happy🇨🇦🇨🇦👍👍
I have been keeping up with all of this series. This is a thing of beauty. I really hope you can post a clip of the block running when the customer finally puts it back in the car!
I've been around machine shops for twenty years, but never around one that specializes in engine work. These videos are interesting from both a machining perspective and a car enthusiast perspective. The machines are not what I'm used to but their function is obvious and the specialization is intriguing. Keep em coming; I could watch that honing machine sling oil all day.
Always listen to the cleaning guy. He often has some useful information and ideas.
I've been an aircraft and tooling machinist for about 15 years and I can say that your practices and processes are top notch! I wish that we had guys like you in our shop 😆
I always wanted to be an automotive machinist, worked in one for a month but they only had me removing broken exhaust bolts. Worked since1976 as Diesel Mechanic and Heavy Equip. Mechanic. I do own a Bridgeport mill and a Takisawa 1000 lathe. I have fun with them and the rest of my toys.
That was beautiful work on that Jag.
It's great you have your dad around truly a master of his craft
Featured on Jalopnik, so I watched it. The whole video. Fascinating. I "knew" how a metal shop works on engines, but to have it so well narrated on such a beautiful job was just awesome. As for whether you're an artist or not, check out 17:00-17:20 in the video and re-evaluate. Art for art's sake!! (MGM's motto in English.)
There's a machine shop and there's an artisanal machine shop. I love your stuff! Thank you.
Your commentary during the video is concise and easy to understand, it brings an added air of expertise to your work.
Thank you
You guys are artists!!! They should stick this block in an Art Gallery for all to see.
I agree, that block is a piece of art. The owner is blessed to have top talent bring his block to significantly better than factory quality. Top work gents
Pretty smart cleaning guy. He should get a raise.
That repair was a thing of beauty! American excellence at its finest. I did hobby rebuilds 50 yrs ago, always in search of a machine shop like yours.
It is such an education watch these videos, I jump on them as soon as they are uploaded. Thanks. The 4.2 block work is amazingly.
You should probably give the cleaning guy a job, he sounds like he knows what he's talking about!
The way you call your dad the cleaning guy is just amazing.
ive loved this whole process, get a video of it running after its done!
I would say after the machine work is done and assembly is complete this baby will rock!
Such a good job on this Jag engine re-sleve it was almost hypnotic watching all the boring & honing processes, the finished job was definitely better than factory!
