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!

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.

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 !

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. 😊

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

The cleaning guy has become such a star ⭐️ recently… I’d forgotten what he was like early doors.

Craftsmanship, pure and simple. Doesn't come any better. A pleasure to watch.

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.

Absolutely stellar work. With men like you and your father it seems anything is possible.

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!

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!

Always a joy to see a craftsman taking a genuine pride in their work.

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 have watched this block from the beginning and was sure it was scrap. What a transformation. Awesome work (even the cleaning guy)!

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.

The owner of this Jag is lucky to have you guys to do the machining. Very interesting, and informative.

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!

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.

Always a pleasure to watch a true craftsman ply his trade. You and your father do beautiful work.

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.

Thanks for being an integral part of keeping the machines we love so much on the road.

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

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 am a retired Automotive Machinist/Instructor. I love watching your videos. You both demonstrate mastery of your skill/profession.

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!

I’ve watched a many hours of KZfaq 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 love to see precision work done by an expert. So satisfying.

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.

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.

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.

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.

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!

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.

Thanks for taking the time to share this series of videos. Excellent work!

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!

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!!

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 ! 😁

You do beautiful work. Nothing wrong with taking pride in your craftsmanship.

Excellent video! Love seeing your family machine shop do these rebuilds! The longer the video the better!

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!!!!

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!

I see JAMSI ... I must see 👀

You folks are true artisans with spectacular attention to detail and equally spectacular results. I didn’t think that block could be salvaged much less rebuilt with factory spec pistons. Unfortunately that quality of work you’re doing is very tough to find these days. Keep the great content coming.

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

Love your content keep it up😊

Agree, the finished product is a thing of beauty.

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.

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.

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.

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 😉

Excellent work. The sheer amount of research and looking deep into this vintage block speaks volumes. I really love the joy of watching you two work together. And thank you to the Belgium folks who added their knowledge to assist you. Thank you both for the very top quality of the work you do. Jim H.

Absolutely amazing work, the attention to details and your push for quality are real attributes for your company! Thanks for sharing your work.

Just ran across your channel and I am hooked! I've always been fascinated by machining and your videos are incredibly well done! Love seeing you and your dad working to keep a small business like this alive, along with the craftsmanship as well - keep up the great work...

That cleaning guy is worth his weight in gold! Make sure you keep him around as long as possible! 🙂👍🏻🇳🇱

Enjoy seeing you and your Dad work together. As a huge Euro car fan, seeing the work on the XK engine was about perfect. Thank you. Would love to see more of that type of work. As long as it’s profitable !

Really enjoyed the journey of this engine block. Fascinating process.

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.

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.

This is amazing. Definitely my new favorite channel, and I look forward to seeing more! Getting ready to send two LM7 blocks to the machine shop local to me, one for just a rebuild and one for a performance build. Keep up the good work!

Great respect for helping an old jag back on the road ...they need all the love they can get !

The work done here is truly amazing. And the results show. Being in and around engineering, software, electrical and CNC, sloppy work shows. Just makes me happy to see how this turned out and the care + attention to detail along the way.

Amazing transformation. I've been watching this series as well as many of your other videos and the quality of work you guys put out is fantastic. I'm a Coloradan myself so next time I need any machine work I'll be sending it your way.

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👍👍.

Really love your gentle and detailed walk through your range of projects: this was a favourite and a great save.

Many thanks for taking the time to film and share all this process. Really love this episode.

Awesome. Just watched this whole series back to back. Fascinating insight into what goes on at a machine shop.

Wow ...that's bloody fantastic. I was looking forward to watching this particular update of this engine to see if it was actually salvageable. Thank you guys. Really interesting videos.

Fascinating!!!! I had no idea there were so many steps. I’ve watched this all the way through, and I’m amazed. !!!!

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

Another great job, thanks for the step-by-step explanations. I'm really looking forward to the next precision machining.

Love the videos! It’s so cool to see a man make a machine do everything he wants and no more. Happy for you!

Top quality work and videography. Perfect mix of technical explanation and satisfying machining sounds.

Very nice. I really thinks it's better than new. I am glad that there is people like you doing and learning this craftsmanship. Thank you.

I started watching yall from your FB shorts. I work at an old metal stamping/ machining shop. Its so satisfying to watch this. It really is calming to me. Great work!

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 😆

Excellent work. I wouldn't hesitate to use your services. The amount of cleaning you do for each procedure you perform on the engine is absolutely amazing compared to some shops I have had to use in the past.

Love the series on the Jag six cylinder. The block looked bad, and I was worried, but you did a great job saving it. Be proud. You are artists. Especially that clean-up guy!

I watched all the videos regarding this restoration. Fascinating and you guys really are artists. I love watching your content.

Your commentary during the video is concise and easy to understand, it brings an added air of expertise to your work. Thank you

Greetings from England! I really enjoyed watching the Jaguar series, what great and careful work, and nice explanations as to what is happening, and why. The block really did look like scrap when you received it, but it left you looking better than new, and good for many trouble free and happy miles ahead! The owner should be delighted to have retained his car’s matching numbers status. It would be fabulous to see the completed engine rebuild back in the car and running, but I guess that you often don’t get to see that yourselves. Best wishes for the Christmas season, and thanks again.

Outstanding! I always learn more everytime i watch. I am not a machinist although I do precise hand blueprinting of high performance engines. The knowledge i pickup helps discuss & evaluate machine operations I commission. Thank you!

Stunning work! Incredibly detailed with perfection as the goal. That block DID look like a work of art!

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

Great work! Thanks for the master class! The detail of the work you and "THE CLEANING GUY" do is seriously impressive. Thanks again!

Great work on this one. I am impressed with how you really saved the block. You really proved your machinist skills and determination. The cleaning guy has skills too.

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.

This project is what brought me from just watching the shorts to watching the full videos. You guys kick ass!

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!

Thank you for Staying Classic and doing excellent quality work. Double and triple check can never be wrong. I enjoyed watching

I love watching your videos. Engine work has a special place in my heart. It harkens back to another era of the older gasser engines where being part engineer and mechanic was more than just a desire but also an incredible occupation of thousands of hours of worthwhile time spent. I was just a boy watching my dad tear down the engine of his “work car” - a 1952 Chevy, and rebuild it. Talk about back in the day when that was feasible! With those skills it meant you could keep the “ol’ jalopy” on the road almost indefinitely. Man, those we’re the days.

What a magnificent rehabilitation of a phenomenal piece of history. It's an absolute honor to share time & space on this little blue marble with folks like you. Thank you so very much for sharing this content.

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....

Love the channel and all the work you do to make these vids for us !! Been a subscriber for long time and I'm always impressed with the quality of detail and work you and pops do ! Keep up the good work everyone 👏

Very satisfying, thank you for your craftsmanship and effort in producing these videos.

I appreciate the attention to detail and accuracy you take on all your work. I would gladly pay you, knowing that you did your best on my machining. Thank you

What a joy to see such careful, thoughtful work, from diagnosis to final hand cleaning.

Loved watching all the episodes on this job. Really impressed by your work ethic and humility.
